Force and Mass

100

A pull or push that is applied to an object

Force

200

2 examples of force not including cars

Opening a door, pushing something across a table, picking up a backpack, etc.

300

Force = mass X __?___

With the same amount of force, will a heavier object (more mass) accelerate faster or slower?

Acceleration; Slower

400

What happens when forces are unbalanced?

If force are unbalanced then there is an change is speed direction or both.

500

The force that opposes an object as it moves along a surface

Friction

Friction and Forces

100

Does friction slow things down or speeds things up?

Slows things down

200

What has more friction, a ball rolling on grass, or a ball on a paved road?

A ball rolling on grass has more friction

300

What is speed?

the distance traveled over time, but does not include direction

example: 25 miles/hr

400

30N            60N                   

---->OBJECT<----         

What is the Net Force acting on the object?

30N left/west

500

What is Newton's 1st Law

An object at rest will stay at rest, and an object in motion will stay in motion, unless acted on by another force

Newton's Laws

100

What is Newton's 2nd Law?

The force exerted by an object is equal to the mass of that object times its acceleration   F=m*a

200

What is Newton's 3rd Law?

For every action there is an equal and opposite reaction

300

Example for Newton's 1st Law

If you kick a ball it will eventually stop due to friction

If you kick a ball into a net the net will stop the ball

400

Example for Newton's 2nd Law

The heavier an object, like a rock, the more force needed to move it than a lighter object

500

Example for Newtons 3rd Law

In a rocket, hot gases are releases downward and an equal upward force pushes the rocket forward
