opposite

Front

What would happen if a person sat on a chair and the chair did not exert an equal force back?

Back

The person would fall to the floor.

Front

Which of Newton's Laws states that an object's force depends on an object's mass?

Back

Newton's 2nd Law of Motion

Front

What is the first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the force is constant.
