How to Calculate Kinetic Energy (KE)

This video tutorial explains how to calculate kinetic energy using the formula KE = MV^2/2, where M is mass in kilograms and V is velocity in meters per second. It emphasizes the importance of following the order of operations, particularly squaring the velocity first. The tutorial includes two examples: calculating the kinetic energy of a car and a baseball, demonstrating the step-by-step process of plugging values into the formula and solving for kinetic energy. The video also highlights the significance of using correct units and understanding the concept of kinetic energy.

What is the formula used to calculate kinetic energy?

• M plus V squared divided by two

• M squared V divided by two

• MV squared divided by two

• MV divided by two

In the car example, what is the first step in solving for kinetic energy?

• Add mass and velocity

• Square the velocity

• Divide mass by velocity

• Multiply mass by velocity

Why is the kinetic energy of the car a large number?

• The car is very light and moving slowly

• The car is very heavy and moving slowly

• The car is very heavy and moving fast

• The car is very light and moving fast

In the baseball example, what is the mass of the baseball?

• 2.0 kilograms

• 1.75 kilograms

• 1.5 kilograms

• 2.5 kilograms

What is the final kinetic energy of the baseball?

• 941.36 Joules

• 750.25 Joules

• 850.50 Joules

• 1000.00 Joules
