What is Newtons 1st law of motion?

• Force= Mass multiplied by acceleration 
• An object at rest stays at rest unless acted on an unbalanced force. (inertia)
• For every action there is a equal and opposite  re-action.
• law of gravity 

What is Newtons 2nd law of motion?

• Pancakes 
• Force= Mass multiplied by acceleration
• For every action there is a equal and opposite  re-action.
• Law of gravity 

What law of motion does this picture represent?

• Newtons 1st law
• Newtons 4th law 
• Newtons 3rd law 
• Newtons 2nd law

A net force of 15 N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the encyclopedia?

•  m = 3.0 kg
• m = 4.0 kg 
• m = 3.0 ml 
• m = 30.0 g

Determine the accelerations that result when a 12-N net force is applied to a 3-kg object. 

• 3 m/s
• 4 ft/s 
• 13 m/s
• 4 m/s 

For every action there is a equal and opposite...

Mass is a measure of an object's inertia. Objects with greater mass have a greater inertia; objects with less mass have less inertia.

• true 
• false
