Kinetic and Potential Energy Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, commonly associated with gravitational potential energy, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Where is kinetic energy maximum on a roller coaster?

Back

At the bottom of a big hill.

Front

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

What happens to kinetic energy as an object speeds up?

Back

Kinetic energy increases as the speed of the object increases.

Front

What happens to potential energy as an object is lifted higher?

Back

Potential energy increases as the object is lifted higher.

Front

How does mass affect kinetic energy?

Back

Increasing an object's mass will increase its kinetic energy, as kinetic energy is directly proportional to mass.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

At which point in a pendulum's swing is potential energy greatest?

Back

At the highest points of the swing.

At which point in a pendulum's swing is kinetic energy greatest?

Back

At the lowest point of the swing.
