Front

What is the force that pulls objects toward each other, such as an apple falling from a tree?

Back

Gravity

Front

True or False: Potential energy is determined by an object's mass and height, while kinetic energy is determined by an object's mass and speed.

Back

TRUE

Front

Which point in a motion graph typically has the greatest kinetic energy?

Back

C

Front

What happens when two magnets with the same poles are brought close together?

Back

They repel each other.

Front

According to the law of universal gravitation, what do all objects in the universe that have gravity possess?

Back

Mass

Front

What is potential energy?

Back

The energy stored in an object due to its position or state.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy = 1/2 * mass * speed^2

Front

What is the relationship between mass and gravitational force?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What is the effect of height on potential energy?

Back

The higher an object is, the more potential energy it has.
