Why do you keep moving forward after a car stops suddenly?

• Your inertia keeps you moving forward

• You lose your backward force

• Your mass keeps you moving forward

• The forces on you are not acting at that time

The more mass an object has: (choose all that apply)

• The more force is needed to move it

• The more force it can apply

Newton's 2nd law states that:

• Gravity = 9.8 m/s²

• S = d/t

• F = m x a

• D = m/v
