Front

What is potential energy?

Back

Potential energy is the energy due to an object's position or condition.

Front

At which points is potential energy greatest in a pendulum swing?

Back

Potential energy is greatest at points 1 and 5.

Front

What is kinetic energy?

Back

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

Front

What is the Celsius scale?

Back

The Celsius scale is a temperature scale where water freezes at 0 degrees and boils at 100 degrees.

Front

What is the speed of a man who runs 10 miles in 1 hour?

Back

The speed is 10 miles per hour.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest points, and kinetic energy is highest at the lowest point.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to temperature.
