Newton's Second Law of Motion

Front

What unit do we measure force in?

Back

Newtons

Front

True or False: The force that pulls an object in a circular motion and keeps it in a circular motion is centripetal force.

Back

True

Front

If Football A has a greater mass than Football B, which football will have greater acceleration when both are thrown with the same force?

Back

Football B will have greater acceleration.

Front

What happens to a ball rolling on the floor when a force pushes it in the same direction?

Back

The ball will go faster.

Front

What is the direction of the centripetal force on a horse galloping around a circular arena?

Back

Directed toward the center of the arena.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a)

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.

Front

What is inertia?

Back

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

Front

What is an example of centripetal force in everyday life?

Back

A car turning around a curve.
