Newton's Laws of Motion

What is Force?

• A push or pull

• The distance traveled by a body unit.

• Speed at a certain time

What is the measurement of Force?

• Jules

• Meters/second

• Newtons

• Kilograms

What is Newton's First Law?

• For every action force, there is an equal but opposite reaction force.

• An object will not change its motion unless acted on by an unbalanced force.

• Accelerations determined by the net force acting upon the object and the mass of the object.

What is the formula for Newton's Second Law?

• F=ma

• F=m/a

• F=a/m

• F=dt

Newton's Third Law states:

• For every action force here is an equal but opposite reaction force.

• An object will not change is motion unless acted on by an unbalanced force.

• F=ma

Which is an example of Newton's First Law?

• A climber pulls down on a rope causing his body to lift upward and rise along the rope.

• It is much easier to carry your backpack when it is empty rather than when it's full of textbooks.

• For every action there is an equal and opposite reaction.

• When you are standing in a subway train and the train suddenly stops but your body continues to move forward.

Which is an example of Newton's Second Law?

• When you give your friend a lift on your bike you have to pedal harder and faster to keep the same speed (acceleration) as you had when you were on your bike alone.

• A climber pulls down on a rope causing his body to lift upward and rise along the rope.

• When you are standing in a subway train and the train suddenly stops but your body continues to move forward.

Give an example of Newton's Third Law:

• A smaller cannon ball leaves a cannon much faster than a larger, heavier cannon ball fired at the same time.

• A climber pulls down on a rope causing his body to lift upward and rise along the rope.

• A boy is going down a slide. As he reaches he bottom, friction causes him to slow own and stop.
