What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a marble at the top of a hill has potential energy because of its height.

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

At which location does a marble have maximum kinetic energy when rolling down a track?

Back

The marble has maximum kinetic energy at Location Y, where it is moving the fastest.

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and can cause an object to start moving, stop moving, or change direction.

What does a graph showing a car slowing down look like?

Back

A graph showing a car slowing down will have a downward slope, indicating a decrease in speed over time.

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

If the net force on an object is 40 N to the right, what does this mean?

Back

It means that the object will accelerate to the right due to the unbalanced force acting on it.

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

What is the effect of an unbalanced force on a stationary object?

Back

An unbalanced force will cause a stationary object to start moving in the direction of the force.
