Brain Pop: Newton's Laws of Motion

Front

What happens if an unbalanced force acts on an object?

Back

The object will accelerate in the direction of the force.

Front

What does Newton’s second law state about acceleration?

Back

Acceleration depends on mass and the amount of force applied.

Front

What occurs when you push against a wall according to Newton's third law?

Back

The wall pushes back at you with the same amount of force you applied.

Front

What part(s) of a moving car experience the most friction?

Back

The tires experience the most friction.

Front

What does Newton's third law state about forces?

Back

Forces always occur in equal and opposite pairs.

Front

What is inertia?

Back

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

Front

What is the formula for Newton's second law?

Back

F = ma (Force equals mass times acceleration).

Front

What is the relationship between mass and acceleration?

Back

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

Front

What is an example of Newton's first law?

Back

A soccer ball will not move until a player kicks it.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.
