Calculating energy and work

Question 1

rule for calculating kinetic energy for an object

Answer 1

KE = 1/2 (mv2)
m = mass (kg), v = velocity/speed (m/sec)

Question 2

rule for calculating gravitational potential energy for an object

Answer 2

GPE = m x g x h
m = mass (kg), g = acceleration due to gravity (10 m/s2)
h = height (m)

Question 3

What is meant by the term Work?

Answer 3

process of energy transfer that occurs when a force is applied to an object causing it to move.

Question 4

rule for work calculations and perform simple calculations of work, force and distance.

Answer 4

W = F X d
W= work (J), F= Force (N), d=distance (m)
