Forces Flashcards
1
Q
What is the formula for force?
A
Force = Mass * Acceleration
2
Q
When are 2 forces balanced?
A
When 2 forces are balanced when they are same in size but act in different directions
3
Q
How will it move when the forces on an object are balanced?
A
It will move at constant speed in one direction or remain at the point
4
Q

A
It will speed up (accelerate), slow down (decelerate) or change direction.
5
Q
A cyclist of mass 60kg rides a bike of mass of 20kg. When starting off the cyclist provides a force of 200N.
What is his acceleration?
A
200 = 80 * A
A = 200 / 80
= 2.5 m/s^2
