Review Q #2

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy increases with the mass of the object and its height above the ground.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces acting on it are combined.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What does it mean when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the net force.

Front

What is an example of gravitational force?

Back

An example of gravitational force is the force that pulls an apple toward the ground when it falls from a tree.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

How does pushing against water allow a person to move forward in a kayak?

Back

When a person pushes backward against the water with a paddle, the water pushes back with an equal and opposite force, propelling the kayak forward.
