What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

According to Newton's second law, if you increase the force applied to an object :

• it accelerates more
• it doesn't move
• you get more inertia
• it decelerates

What is Newtons 2nd law of motion?

• Law of inertia

• Force = Mass multiplied by acceleration

• For every action there is a equal and opposite  re-action.

• Law of gravity
