What is unequal forces pushing in opposite directions?

When unequal forces push in opposite directions on an object, the object will experience a net force in the direction of the stronger force. This can result in the object moving in the direction of the stronger force or experiencing a change in its state of motion.

What are the three types of forces according to newtons first law?

Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object (if all the external forces cancel each other out), then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. And if an additional external force is applied, the velocity will change because of the force. The amount of the change in velocity is determined by Newton's second law of motion.

How are action and reaction forces related?

They are equal and opposite (Newton's third law).Each action has an equal an opposite reaction. For example: pulling on a rubber band and letting it go will cause it to fly around. This is the action and related response or reaction desired.

What is the opposite force to Friction?

Well, there are several ways to go about answering this.

Inertia is the property of an object at rest resisting motion.

First: Pmomentum is the property of an object in motion to resist change in that motion.

Second: Potential Energy is the property of an object at rest to begin moving, it typically results from height.

Third: Kinetic Energy is the property of an object in motion to keep moving. [here both of our categories are opposite of inertia] This is likely the best bet.

Any of these are good options if your answer is limited to the field of Fizex. (Then again, Quantum physics is fairly different from inertia too.)

Finally: If your answer isn't related to Fizex, Waffles, Historical figures, language, and philosophy are very different from Inertial.

Is rolling friction greater than sliding friction?

Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.

Calculate velocity of a gas?

Gas velocity involves the variables of system temperature and molar mass of its molecules. Simplified, the velocity as a root-mean-square equals the square root of two-times the kinetic energy divided by molecular mass.

What is the Amplitude of a signal measure?

The amplitude of a signal is the measure of the maximum magnitude of the signal from its equilibrium value. It represents the strength or intensity of the signal. A higher amplitude indicates a stronger signal, while a lower amplitude indicates a weaker signal.

Is impulse the same as momentum true or false?

False. Impulse and momentum are related concepts but not the same. Momentum is the product of an object's mass and velocity, while impulse is the change in momentum experienced by an object when a force is applied to it over a period of time.

Can action and reaction forces cancel each other?

Well, let's put on our thinking caps here:

If you're trying to push a car, and you can't quite do it alone, you call your friend

over and ask him to help you. So he comes over, and he stands next to you, and

which way does he push . . . in the same direction as you're pushing, or in the

opposite direction ?

Which direction helps you move the car, and which direction would make the two

of you look like Laurel and Hardy, and transform the both of you into objects of

derision and scorn ?

Can an object have a northward velocity and southward acceleration?

Yes, an object can have a northward velocity and southward acceleration. This situation occurs when the object is moving northwards but its speed is decreasing or it is changing direction towards the south.

State newtons first law?

Newton's first law of motion is often stated as An object at rest stays at rest and an

object in motion stays in motion with the

same speed and in the same direction unless acted upon by an unbalanced

force
Objects that are in motion will stay in motion unless they are acted upon by an outside force; objects that are not moving will stay still unless they are acted upon by an outside force.

How much force does it take to keep an object moving in a straight line at a constant speed?

To keep an object moving in a straight line at a constant speed, you need to apply a force equal to the force of friction or any other resistive forces acting on the object. This force is called the net external force and is equal in magnitude but opposite in direction to the sum of all resistive forces.

Define newtons first law of motion?

a body remains at rest or in motion with a constant velocity unless acted upon by external force.

An object in 3 dimension space is called?

An object in 3-dimensional space is called a three-dimensional object or a 3D object. These objects have length, width, and height, making them appear solid and taking up space in all directions.

What is an example of interia?

Feel a forward jerk on your body when bus stops suddenly, or a backward jerk when bus starts forward.

A roller coaster car operates almost entirely on inertial energy.

Coasting on a skateboard, bicycle, or manual scooter.

A rock sitting on the ground (not moving without added energy).

A resting object exerts pressure equal to?

that is equal to its own weight, newton's 3rd law, action and reaction are equal and opposite

What are the examples of equilibrium?

Examples of equilibrium include a book sitting on a table, a ball at rest on the ground, and a pencil standing vertically on its tip. In each case, the forces acting on the object are balanced, resulting in a stable state of rest.

Give you 5 examples of Inertia?

We are subject to the concept of inertia and experience such an idea every single day. Here are some examples.

1. Suddenly accelerating during a car ride makes the driver and the riders feel pushed up against their seats. Inertia explains this phenomenon quite clearly.

2. Turning around a corner while driving makes the driver and the riders move quite counter-intuitively. For example, if a car turns right, every person in the car is pushed to left and vice versa; inertia explains this phenomenon.

3. We usually shake the bottle of ketchup or hit it in order to get that last bit of ketchup remaining in the bottle. We do both of these things to move the ketchup as the remaining bit of ketchup is subject to the idea of inertia when shaken or hit.

4. After sprinting for a while, you must apply a backward force in order to stop. Yet if you do not apply this backward force, you will continue moving forward. If you stop running suddenly, you will for a second move at the speed at which you were running before. Inertia helps to explain this phenomenon.

5. If a bus suddenly stops and you aren't holding onto a support, you will be pushed to the front of the bus. Your mass and the concept of inertia helps to explain such a phenomenon.

Isaac Newton can be credited with all of these except?

Isaac Newton can be credited with most famous for his laws of motion, theory of universal gravitation, and development of calculus. However, he cannot be credited with the invention of the telescope, which is typically attributed to Hans Lippershey.

On beating a carpet why do the dust particles come out?

Because when you shake it the particles break free of the threads!

How does the viscosity of sea water qualitatively vary with temperature?

between 0 Celsius and 20 Celsius the dynamic viscosity of seawater at 35 g/kg salinity is reported to be 1.88 x 10-3 and 1.08 x 10-3 Pa s. If you calculate the rate of decrease in viscosity with increasing temperature you get -0.04 x 10-3 Pa s per degree.

What are the different science process skills?

The different science process skills include observation, communication, classification, measurement, inference, prediction, and hypothesis formation. These skills are essential for conducting scientific investigations and interpreting data accurately.

Formula for mechanical energy?

The formula for mechanical energy is the sum of kinetic energy (KE) and potential energy (PE), where ME = KE + PE. Kinetic energy is given by KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. Potential energy depends on the type of potential energy involved, such as gravitational potential energy (PE = m * g * h) or elastic potential energy (PE = 0.5 * k * x^2), where m is mass, g is gravitational acceleration, h is height, k is the spring constant, and x is the displacement from equilibrium.

According to newtons seond law of motion?

According to Newton's second law of motion, the acceleration of a body is directly proportional to the net force and inversely proportional to its mass. a = F/m

This law is most often used relating force to mass and acceleration, in which the net force is directly proportional to a body's mass and acceleration, F = ma.
