2Q Review

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

What happens when an object is in motion and experiences a net force of zero?

Back

The object will continue to move at a constant velocity or remain at rest.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What is Newton's third law of motion?

Back

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

Front

What is an example of potential energy?

Back

A stretched rubber band or a rock held at a height.

Front

What is an example of kinetic energy?

Back

A moving car or a rolling ball.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is at rest.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates that the object is moving quickly.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
