Forms of Energy and Energy Transformations

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

Which position has the greatest gravitational potential energy?

Back

The position that is highest above the ground has the greatest gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

At what position does an object have the greatest kinetic energy?

Back

An object has the greatest kinetic energy at the position where it is moving the fastest.

Front

What is potential energy?

Back

Potential energy is stored energy that results from the position or shape of an object.

Front

How can you determine if lights are connected in series or parallel?

Back

Unscrew one light. If the other lights turn off, it’s a series circuit.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, all components are connected end-to-end, so if one fails, the entire circuit stops. In a parallel circuit, components are connected across common points, so if one fails, others can still operate.

Front

What is the formula for calculating kinetic energy?

Back

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

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 type of energy is associated with the temperature of an object?

Back

Thermal energy is the energy associated with the temperature of an object.
