Newtons Laws of Motion

Force

is a push or pull

Inertia is...

the tendency for an object to resist a change in motion

Newtons 1st law of Motion says...

An object at rest stay at rest and an object in motion stays in motion until by unbalanced force.

Newtons 2nd law of Motion says...

acceleration is based on an objects mass and force applied to it

Newtons 3rd law of Motion says...

For every action there is an equal and opposite reaction.

F=m*a

What is the equation for Force?

Newtons

What units is Force measured in?

Balanced forces

cause no change in motion

They are in motion and want to stay in motion

Why do the blocks fly off the car when it crashed into the wall?

They are at rest and want to stay at rest

Why does the clothes pin fall into the cup when the card is moved?

Small rock

Which of the rocks will have the greatest acceleration if pulled with 50 N of force?

3rd Law example

The balloon is an example of which law?

1st Law example

This is an example of which law?

2nd Law example

Which law is this an example of?

Velocity

Speed in a given direction

20 N

How much force is required to move a 10 kg object that is accelerating at 2 m/s?

5 m/s^2

How fast will an object accelerate if it mass of 2 kg and its pushed with a force of 10 N?

5 N

If your friend is pushing on a box with 10 N of force and you're pushing the opposite side with 5 N of force. What is the net force acting on the box?

0 N-not moving

If your friend is pushing on a box with 20 N of force on the left and you're pushing the right side with 20 N of force. What is the net force/direction of the box?

B

At which point is speed constant?

50mph

What is the speed of an object that travels 100 miles in 2 hrs?

Rest/stop

What does the line represent on this distance vs. time graph?

.5 hour

If you are going 60mph, how long will it take you travel 30 miles (T= D/S)
