Kinetic Energy

Question 1

What is the formula to calculating kinetic energy?

Answer 1

Kinetic energy = 1/2mv ²

m = mass, v = velocity.

Question 2

What are the three steps to calculating KE?

Answer 2

Step One: WRITE THE FORMULA, Step Two: SUBSTITUTE THE VALUES and Step Three: EXPRESS THE ANSWER WITH CORRECT VALUES

Question 3

What is the KE of an object is its mass 5kg and its moving at the speed of 4m/s?

Answer 3

The KE of the object would be 40.0J

Question 4

How do you calculate velocity from mass and KE?

Answer 4

√ 2KE/M (2 times KE divided by mass and square rooted)

Question 5

How do you calculate mass from KE and V?

Answer 5

2KE/V ² = M
