A
As long as the forces on an object are balanced, then it’ll just stay still it carry on at the same velocity
2
Q
What is Newton’s second law of motion?
A
If there is an unbalanced force, then the object will accelerate in that direction
3
Q
What is Newton’s third law of motion?
A
If object A exerts a force on object B, then object B exerts the exact opposite force on object A
4
Q

A
It’s drag (shape and area) compared to its weight
