Questions and Answers

What does Newton's 1st Law state about an object in motion?

It will continue moving only if acted upon by another object.
It stays in motion with the same speed and direction unless acted upon by an unbalanced force. (correct)
It changes direction randomly after some time.
It will eventually lose speed.

According to Newton's 2nd Law, what happens when force applied to an object increases?

The mass of the object decreases.
The object's speed remains unchanged.
The acceleration decreases proportionally.
The acceleration of the object increases. (correct)

Which example best illustrates Newton's 3rd Law?

A car slowing down on a road.
A ball rolling on the ground.
A person pushing against a wall. (correct)
A pencil resting on a desk.

Newton's 1st Law of Motion

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.

Newton's 2nd Law of Motion

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the greater the force, the greater the acceleration, and the greater the mass, the smaller the acceleration.

Newton's 3rd Law of Motion

For every action, there is an equal and opposite reaction.

Example of Newton's 1st Law

When a skateboarder hits a rock, their motion stops due to the unbalanced force of the rock. The rider continues moving until friction or an outside force stops them.
