• increase

An object at rest will stay at rest and an object in motion will stay in motion, unless acted upon by an unbalanced force.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Force is equal to mass multiplied by acceleration.

(AKA an object that weighs less with take less force to move)

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

A student pushes a box to right with a force of 10N while a young boy pushes the box to the left with a force of 8N. What is the sum of all forces on the box? 

(First think, "do you add or subtract those numbers?")

• 18N left

• 2N right

• 18N right

• 2N left

Answer explanation

You needed to subtract because they went opposite directions:

force of 10N to the right - force of 8N to the left

2N to the right (because the one pushing right had more force so it "won")

What is the formula for finding acceleration?

• a = F/m

• a = m/F

• F = a/m

• m = F/a

Answer explanation

Acceleration = Force / mass
