Three laws of motion 

1. Balanced Forces mean NO velocity

As long as the forces on an object are all balanced. Then it'll just stay still or it's already moving will carry on at the same velocity.

2. A resultant forces means acceleration 

If there is an unbalanced force, then the object will accelerate in that direction. 

The acceleration can take five different forms;

  • Starting
  • Stopping
  • Speeding up
  • Slowing down
  • Changing direction 

The bigger the force, the greater the acceleration or deceleration.

The bigger the mass, the smaler the acceleration.

To get a big mass to accelerate as fast as a small mass it needs a…
