Slide 11

“An object at rest remains at rest unless acted on by another force.”

An object will stay at rest or “look still” until you do something to make it move.

The toy car stays at the starting line (at rest) until you push it (apply a force).

The hockey puck sits on the ice (at rest) until you push it with the stick (apply a force).

Slide 13

Newton’s 1st Law of Motion

What happens when the track curves left or right?

The train turns and goes left or right

Slide 14

“An object in motion in a straight line tends to say in motion in a straight line unless acted upon by another force.”

An object will go straight until a force makes it go another direction.

Your paper airplane flies straight until gravity pushes it down.

Thomas drives straight until the driver makes it “turn” with the track.

Slide 15

Let’s see what we’ve learned so far about motion!

Give this quiz a try and test your motion knowledge!

YOUR TURN!!

Slide 16

Any object that is moving.

Any object that flies.

Any object that drives on the road.

Any object this is sitting still.

What is motion?

Slide 17

You’re right!

Motion is described as any object that is moving!

GREAT JOB!

Slide 18

Anything that is moving is in motion.

We can say motion is any object that is moving.

Try the question again!!

Try Again

Slide 19

What force do you apply to move a toy car?

A pull

Turning the key

Throwing it

A push

Slide 20

We have to “push” the toy car to put it into motion!

You’ve really been paying attention!!

GREAT JOB!!

Slide 21

Think about what we have to do to get that toy car moving.
