Front

What should you do first if you are injured in the laboratory?

Back

Tell the science instructor at once.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy.

Front

What type of energy does a moving object possess?

Back

Kinetic energy.

Front

How does the speed of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the unit of force?

Back

Newton.

Front

What is the definition of kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the definition of potential energy?

Back

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

Front

What happens to potential energy when an object falls?

Back

It is converted to kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).

Front

What is the formula for calculating potential energy?

Back

PE = mgh (where m is mass, g is acceleration due to gravity, and h is height).
