IPC Physics Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as Speed = Distance/Time.

Front

What can be transformed from one type to another while the total amount remains constant?

Back

Energy can be transformed from one type to another, yet the total amount of energy always stays the same.

Front

What type of energy is elastic energy?

Back

Elastic energy is a form of Potential energy.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = ½mv².

Front

What type of energy does a roller coaster have at the top of the first hill?

Back

At the top of the first hill, a roller coaster has mostly Potential energy.

Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What happens to energy in a closed system?

Back

In a closed system, energy is conserved; it can change forms but cannot be created or destroyed.
