Newtons Laws of Motion

A mass accelerates uniformly when a constant force is applied to it, resulting in a constant rate of change in velocity over time. This occurs in scenarios where there is no opposing force or acceleration due to factors such as friction, air resistance, or gravity.

1. As you walk, newton's third law is inherent in it. First you lift your say right leg and put it forward. Now your weight will be totally acting on the left leg. Now you push the earth with your left leg. This is action. Then equal and opposite reaction makes you to move forward ie you centre of gravity would be moved forward and the whole weight would rest on the right leg.

Now the previous process gets repeated again again.

2. You'd like to get up from the chair. Your weight rests on the base of the chair. Now with your legs on the floor, you push the floor downward. This is action. Due to opposite reaction now you are able to lift your centre of gravity vertically up and so you can come out of chair and able to stand.

3. A car tyre as it starts rotating, it pushes the earth backward. So the rotating tyre would be able to move forward. This is solely due to the presence of friction between the tyre and the road. If suppose the wheel is rotating in mud, then only wheel rotation but nor forward movement. As there is lack of frictional force between the tyre and mud, action and reaction both are absent and hence no forward progress.

You can find the speed of the block using the equation of motion: v^2 = u^2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, and s is the displacement. Given that u = 0.5 m/s, x = 3 cm = 0.03 m (displacement), and a is constant, you can calculate the final velocity v when the block reaches x = 3 cm.

newton's first law of motion is; objects at rest stay at rest and objects in motion stay in motion unless an outside force acts upon it. A term that summarizes this law could be that when a wheelchair is standing still, it is not in motion, the only way that the wheelchair can move is unless an outside force (person) acts on it, causing the wheel chair to change distance.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on a second object, the second object will exert a force back on the first object that is equal in magnitude and opposite in direction.

Obeying the second law of universal dynamics (Newton) , the equation is

F = ma

Algebraically rearrange

m = F/a

The metric units are

m(kg) = F(kgm/s^2) / a(m/s^2)

NB The 'm/s^2' cancel down leaving 'kg'.

NNB The units of force 'kgm/s^2' are known as 'Newtons'.

Gamma waves have the highest frequency (and energy) of all the electromagnetic waves.

Gamma Ray Bursts (GRB) from outer space (and that's about all we know of them!) have extraordinary high energies, and hence frequencies.

No, a puddle of water is typically stationary unless there is external force or movement causing ripples or waves on the surface.

Philosophiæ Naturalis Principia Mathematica, Latin for "Mathematical Principles of Natural Philosophy", often called the Principia ("Principles"), is a work in three books by Sir Isaac Newton, first published July 5 1687.

1. Basketball - Players exert a force when dribbling, passing, or shooting the ball, which changes the ball's velocity.
2. Swimming - Swimmers exert force against the water to propel themselves forward, changing their velocity in the pool.
3. Football - Players exert force when kicking or throwing the ball, resulting in a change in the ball's velocity.

Momentum = (mass) multiplied by (speed) .

Anything moving has more momentum than anything that's not moving. The thing

that's not moving has zero speed, so it also has zero momentum.

The direction of the net force acting on the object at position A depends on the individual forces acting on the object. If the net force is the vector sum of all forces, the direction will be determined by the relative magnitudes and directions of those individual forces.

The average velocity of an object in motion can be calculated by dividing the total displacement by the total time taken. It gives an overall idea of how fast the object is moving over a given distance.

Newton's Second Law is not the definition of force. Force is a push or pull, to put it simply.

Newton states that a force is proportional to the mass and the acceleration of the mass. F=ma.

In other words, it is in a way similar to a "measurement of a force" that a mass exerts on something if it is accelerating. Yet it explains a deep concept that explores the proportionality or relationship between the three variables, force, mass and acceleration.

An unbalanced force occurs when the net force acting on an object is not zero, causing the object to accelerate in the direction of the larger force. Examples include a car accelerating, a ball falling in free fall due to gravity, or an object being pushed or pulled in one direction.

The spring constant of a slinky can vary depending on factors such as the material it is made of, its design, and manufacturing process. Typically, the spring constant of a slinky is around 1-2 N/m.

Assuming the force of friction and the initial force oppose each other the net force is 300 N - 200 N = 100 N in the direction of the initial force.

No

An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.

Acceleration is a change in velocity. More precisely, to get acceleration, you divide the change in velocity, by the time that passed.

When a force acts on an object and moves it, work is done. The work done is equal to the force applied multiplied by the distance moved in the direction of the force. This can result in the object gaining kinetic energy or performing mechanical work.

The Law of Inertia states that a body continues in a state of uniform motion unless a force act on it.

No, the cannon will have less kinetic energy compared to the cannonball due to its smaller mass. Kinetic energy is proportional to an object's mass and velocity, so the faster and heavier cannonball will have more kinetic energy than the slower and lighter cannon.

No, the cannon and cannonball will not have the same amount of kinetic energy when the cannon is fired. The cannonball typically has more kinetic energy due to its higher velocity compared to the slower-moving cannon.
