.

How does the acceleration of a cart depend on the net force acting on the cart if the total mass is constant?

The answer above is correct: if the force is constant,

the mass is inversely proportional to the acceleration

. So if the mass increases, the acceleration decreases, and vice versa.

What happened to the acceleration of the cart as the weights on the holder increase?


Its velocity and therefore acceleration increases

. Adding mass to the cart causes it to take more time to hit the barrier. Its velocity and therefore acceleration have decreased.

What are the two important things to remember in Newton’s 3rd law of motion?

First of all ,

there is a force ,acts on one body , it is called action

. And there is another force, called reaction, acts on an other body. Second , the two forces are equal in magnitude and opposite in direction. Last thing there is no resultant force since the forces acts on two different bodies.

What are Newton’s 1st 2nd and 3rd laws of motion?

In the

first law, an object will not change its motion unless

a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Is inertia the same as Newton’s first law?

law of inertia, also called Newton’s first law, postulate in physics that, if a body is

at rest or moving

at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

What do you have to change in order to change the motion of an object?


A force

can speed up or slow down an object. A force can change the direction in which an object is moving. A bigger force on an object will produce a bigger change in the motion. A heavier object requires a larger force than a lighter object in order to undergo the same change in motion.
