Ch 3 Les 3 Newton's Laws of Motion

Whats Newtons First Law?

• The more force applied to an object the faster it will accelerate.

• An object in motion will stay in motion and an object at rest will stay at rest unless acted by an outside force.

• for every ection there is an equal and oposite reaction

The Law of Inertia

• Newtons 1st Law of motion

• Newtons 2nd Law of motion

• Newtons 3rd Law of motion

The tendency of an object to resist changes in its motion is...

• Acceleration

• Velocity

• Inertia

• Force

Newton's third law states that any action will have a(n) ___ and ___ reaction

• Equal and similar

• Equal and opposite

• Equal and different

• Greater and opposite

What is the standard unit force is measured in?

• Newtons
• pounds
• grams
• meters

Any push or pull on an object.

• force
• velocity 
• inertia
• momentum

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 

Which has more Inertia? (so need more force to move) 

• Truck
• Ant
• A cat
• A skateboard

What pulls a ball back to earth?

• Gas
• Gravity
• Friction
• Molecules

Which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force
