FIRST LAW: BALANCED FORCES = NO CHANGE IN VELOCITY.
If the forces acting upon an object are balanced, the object
would be stationary or moving at the same velocity.
SECOND LAW: A RESULTANT FORCE = ACCELERATION
If there is an unbalanced force acting upon an object, it will de/accelerate in that
This can take 5 different forms:
iii. Speeding Up
iv. Slowing Down
Bigger force = bigger acceleration/deceleration.
Bigger mass= smaller acceleration/deceleration.
To get a larger mass to accelerate, you need a larger force like pushing a heavy
THE THIRD LAW: REACTION FORCES
If one object exerts a force upon another, that object will exert the exact opposite
For example, when pushing your shopping trolley, it will push back against you equally as
hard. When you stop pushing, so will the trolley. The object will still move because there
is a force against it, but so will you. However, the trolley will be accelerated more because
it has a smaller mass.
