• a parked bicycle

What is the formula to calculate kinetic energy?

• 1/2 * mass * velocity

• mass * velocity^2

• 1/2 * mass * velocity^2

• mass * velocity

What is the formula to calculate potential energy?

• PE = 2mgh

• PE = Fd

• PE = 1/2mv^2

• PE = mgh

Explain the concept of speed.

• Speed is the measure of how quickly an object changes color.

• Speed is the measure of how quickly an object changes shape.

• Speed is the measure of how quickly an object moves from one place to another.

• Speed is the measure of how quickly an object changes temperature.

How is speed calculated?

• Speed is calculated by multiplying the distance traveled by the time taken to travel that distance.

• Speed is calculated by subtracting the time taken from the distance traveled.

• Speed is calculated by dividing the distance traveled by the time taken to travel that distance.

• Speed is calculated by adding the distance traveled and the time taken to travel that distance.
