Front

In a tug-of-war, if group B pulls with 400 N and group A pulls with 250 N, which way will the ribbon in the middle move?

Back

Front

Why do safety belts protect people in cars during an accident?

Back

Because the people in the car will continue to move in the same direction and at the same speed as before the impact.

Front

Which object experiences an unbalanced force?

Back

A ball rolling across the floor with friction acting in the opposite direction.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.
