Newtons Laws of Motion

Pushing a ball in a vaccum is an example of inertia because there is no resistence to stop the ball so the ball would keep going.

Well, friend, imagine force as a gentle breeze guiding a sailboat, mass as the size of the boat, and acceleration as how quickly the boat picks up speed. Just like a larger boat needs more force to accelerate, a greater mass requires more force to achieve the same acceleration. It's all about finding the right balance to create smooth sailing!

Yes, Newton's laws can be applied to rotational motion through the concept of torque, which is the rotational equivalent of force. Newton's first law of motion can be applied to rotational motion to understand objects at rest or in uniform rotation. Newton's second law can be used to analyze the relationship between torque, moment of inertia, and angular acceleration in rotational motion. Newton's third law can also be applied to rotational motion to understand the equal and opposite reaction forces that occur in rotating systems.

Absolutely. That's exactly the situation of a rubber ball that was tossed straight up,

at the instant when it's at the top of its arc.

Any object that's not connected to anything else and is rising or falling has constant

acceleration ... the acceleration of gravity. If it was originally launched upward, then

it eventually runs out of steam, stops, reverses direction, and starts moving down.

At that instant during its constant acceleration, its velocity is zero.

The relevant formula here is Newton's Second Law, meaning that you need to divide the force by the mass. If you want to estimate the answer in your head - if that's what you mean by "guess" - you can round the mass to 700 or 800, and the force to 1000 or 1100.

A World Stamp Catalog is often a useful starting point, but they seldom give all the variants, so you may need a good catalog for the country concernced, or you may need to consult an expert. It's also useful to look on eBay, but please bear in mind that in some cases the 'same' stamp may have differences not visible on eBay, such as different watermarks. I suggest to use first the Scott's Catalog (go to your local library). Then you can go to E Bay; but Scott Catalog is the "Bible of Stamps," and you can have a very good idea about the price depending on the type of the stamp you have. You will need to know how to identify the different watermarks, color variations, different perforations, etc. Older stamps may be worth a bit more. High value stamps, the half dollar and up values, are rarer and worth more. To maximize your profits in stamps, you need to fully identify the stamp, including knowing the catalog number, perferations, watermarks, condition and other factors. If you look it up in the catalog there is a price listed. That price is what a buyer should expect to pay a dealer for the stamp. If you are selling, you should consider yourself lucky if you get half that amount. Selling or buying a single stamp is usually not worth the effort to a dealer unless it has a high catalog value. They can make their profits on buying in bulk and selling them in smaller lots. Look for special markings. Stamps on envelopes can be worth more, particularly with picture cancellations, First Day Cancellations and special locations. Find a philatelist and ask for more information!

This situation can be related to Newton's first law of motion, which states that an object in motion tends to stay in motion unless acted upon by an external force. In the case of the cup stopping suddenly, the liquid inside continues to move forward due to inertia, causing it to spill.

Sir Isaac Newton has three laws. They explain the way the mechanical universe operates. That is important to getting around in the universe and understanding all things mechanical that happen.

Newton's third law states every action has an opposite and equal reaction. The consequence of this is you better be careful. You can punch the wall cause your mad but you might also break your fist. You can ram into the jerk who cut you off, but you'll wreck your car to. You can shoot that really cool and powerful looking gun instead of that wimpy looking one at the range, but you might find yourself with some a little more gun in your face than you desire. But most of all it means if you get beat up, you can say he didn't hit my face with his fist, i hit is fist with my face! I know thats an old one...still funny though

No, swimming is not a linear motion. It involves a combination of linear motion (from propelling oneself forward in the water) and rotational motion (from arm and leg movements).

Its easy....

To balance force you need to apply an equivalent force in the opposite direction....

Example:

If a force of 20N acts on a body along the North, you should apply 20N along the south......simple.......

The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.

The relation between force and height is dependent on the context. In the context of work and energy, the force needed to lift an object to a certain height is directly proportional to the height and the weight of the object. In terms of gravitational potential energy, the force acting on an object at a certain height is equal to the weight of the object.

The maximum height of a rocket can be calculated using its initial speed and angle of launch. By analyzing its projectile motion, you can determine the peak height using the equations of motion. The maximum height occurs when the vertical velocity component becomes zero before the rocket starts descending.

Newton's 3rd law requires two forces to be equal and opposite thus summing to zero.

The forces can be represented by the change in momentum thus requiring the momentum be conserved, dP/dt = 0.

0 = Fa + Fr =dPa/dt + dPr/dt =d(Pa + Pr)/dt =0.

Newton's Laws are the manifestation of the Conservation of Energy. The 3rd Law is the vector part of the Conservation of Energy. Conservation of Energy requires that the sum of the Forces sums to zero.

If the forces sum to zero, and Force is the time derivative of Momentum, then the Momentum must be constant. Constant Momentum is the Conservation of Momentum.

Conservation of Momentum is a derivative of the Conservation of Energy and not an independent Law of Conservation as proposed by many including Emmy Noether.

The Conservation of Momentum is the vector part of the Quaternion Conservation of Energy. The Scalar part is said to be the Conservation of Energy. This confusion results from not recognizing that Physics is the science of Quaternion Quantities.

Newton's First Law of Motion, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an external force.

Parallel to the surface of the slope and opposite to the movement of an object on the slope.

Parallel to the surface of the slope and up-slope, in the case of an object resting in place on the slope.

No, an object cannot maintain uniform velocity when its acceleration is non zero. If an object is accelerating, its velocity will be changing over time, so it cannot maintain a constant velocity. Uniform velocity means the speed and direction of the object remains constant.

The passenger jerking forward when a bus suddenly stops can be explained by Newton's First Law of Motion, also known as the law of inertia. This law states that an object in motion tends to stay in motion unless acted upon by an external force, such as the sudden stop of the bus which causes the passenger to continue moving forward.

Newton's first law, the law of inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. It applies to objects in both motion and at rest.

Yes, distance, time, and speed are important in measuring motion. Distance is the amount of ground covered, time is the duration of the motion, and speed is how fast an object is moving relative to a reference point. These measurements help us understand and quantify how objects move and how they are changing position over time.

The second law states that the net force (F net) equals the mass of the object (m) times the acceleration the object experiences (a).

If you increase m, a will decrease for the same F net.

If you increase F net, a will increase for the same m.

If a increases, then either m has decreased or F net has increased.
