2

Multiple Choice

Forces can cause objects to

1

stop moving only.

2

start moving only.

3

start moving, change direction, or stop moving.

4

change direction only.

3

Forces

  • Forces can stop - pushing, pulling, friction, gravity

  • Change Directions- think about hitting a baseball.

  • Change from potential to Kinetic (moving)

4

Multiple Choice

According to Newton's third law of motion, when a hammer strikes and exerts force on a nail, the nail

1

disappears into the wood.

2

exerts an equal force back on the hammer.

3

creates a friction with the hammer.

5

Newton's Laws

  • 1st Law- Objects in motion will stay in motion; objects at rest will stay rest.

  • 2nd Law- More mass needs more force/ more force = more acceleration.

  • 3rd Law - For every action, there is an equal and opposite reaction.

Multiple Choice

2

Jasmyn

3

Jaylah

7

50/10 = 5 = 100/20

Multiple Choice

Which of the following is an example of increasing friction intentionally?

1

adding grease to gears on a bike

2

throwing sand on an icy driveway

3

waxing skis

14

Friction Reduced or Increase

  • Increase friction because the surface is unsafe or get a better grip - cleats or sand

  • Decrease friction to go faster- like waxing skis or greasing gears

15

Multiple Choice

An object that has kinetic energy must be...

1

lifted above earth's surface.

2

at rest

3

in motion.

4

none of the above

16

Potential vs. Kinetic

Potential- The higher- the more potential

Kinetic is moving.

Think of a Roller Coaster
Getting to the very top is the Potential
When you are flying down the roller coaster that is the kinetic.

17

Multiple Choice

4

The size of your ice skates affects your speed across the ice.

18

Multiple Choice

How is velocity different from speed?
1
Velocity is when an object goes in reverse.
2

Velocity is not at all different from speed.

19

20

3
Heavy objects have less inertia.
4
Heavy objects have more inertia.

22

Multiple Choice

You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
1
It takes you a moment to catch up with the new velocity of the car.
2
You have more inertia than the car, so it takes longer for you to turn left.
3
You had been sitting at rest until the force of the turn set you in motion.
4
The car continued in the same velocity, but you had a different inertia.

23

Multiple Choice

What does the second part of Newton’s first law say about objects at rest?
1
They cannot move unless they have a lot of friction.
2
If they are heavy, they will stay at rest, but if they are light, they will move.
3
They will stay at rest unless an outside force makes them move.
4
They have more inertia than objects in motion.
