2
Q
An object has two forces acting on it. A force forward of 600N and a force acting backwards of 200N.
What is the resultant force?
What will happen to the motion of the object?
A
400N
Forward
3
Q
What is the equation relating resultant force, mass , acceleration
A
Resultant force = mass * acceleration
4
Q
An object falls through the air, it had a mass of 15kg and it is accelerating at 9.8m/s
What is the resultant force
A
15 * 9.8 = 147
5
Q
Work done =
A
Force * distance
6
Q

A
50 * 1.5 = 75 J
