Kinetic & Potential Energy

Front

What is kinetic energy?

Back

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

Front

What additional information is needed to calculate the kinetic energy of an object?

Back

The mass of the object.

Front

At which point does a ball on a ramp have the greatest potential energy?

Back

At the top of the ramp.

Front

Why do scientists study systems?

Back

Scientists study systems because it is easier to understand a system than to process how the whole universe works together.

Front

What does the amount of potential energy in a system depend on?

Back

The position of the objects in the system.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

How is kinetic energy calculated?

Back

Kinetic energy is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

How does mass affect potential energy?

Back

The greater the mass of an object, the greater its potential energy at a given height.
