Understanding Motion and Energy Concepts

Front

What do balanced forces do to an object's motion?

Back

They keep the object in its current state of motion.

Front

What is the difference between speed and velocity?

Back

Velocity includes direction, speed does not.

Front

What happens to a moving object when unbalanced forces act on it?

Back

The object will change its speed or direction.

Front

How does heating a substance affect the kinetic energy of its particles?

Back

The particles move faster and have more kinetic energy.

Front

What is an example of conduction?

Back

A metal spoon getting hot from a pot of boiling water.

Front

Define motion.

Back

Motion is the change in position of an object over time.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
