Newton's Laws of Motion Concepts

Front

What is the sum of forces acting on a particle or body?

Back

Net force

Front

Which Newton's law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by a net external force?

Back

Newton's 1st Law

Front

What type of force is applied when a student runs and kicks a ball?

Back

Unbalanced force

Front

What happens to the motion of an object when a force is applied? Which of Newton's Laws does this represent?

Back

Newton's 1st Law, inertia

Front

If the same force is applied to a bowling ball and a soccer ball, which will move faster? Which law explains this?

Back

Newton's 2nd Law

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is Newton's 2nd Law of Motion?

Back

Force equals mass times acceleration (F = m x a).

Front

What is an example of Newton's 3rd Law of Motion?

Back

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

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force.
