This

What must occur every time for work to be exerted?

A 100


This

  • A force must be applied

  • An object must move in the same direction as the force

A 100


This

  • What unit is used to measure force?

  • What unit is used to measure work?

A 200


This

  • Newtons (N)

  • Joules (J)

A 200


This

What is the formula for work?

A 300


This

Work = force x distance

(W = f x d)

A 300


This

If you lift your science book up off the floor, are you doing work?

Why/why not?

A 400


This

Yes, because you are lifting your books upward, and the books are moving upward also.

A 400


This

You pick your cell phone up off the counter and talk into it as you walk across the room. When you finish talking, you place it back on the counter and slide it away from the edge.

When are you doing work on the cell phone?

A 500


This

  • Picking up the cell phone

  • Placing it down on the counter

  • Pushing it away from the edge

A 500


This

You exert 20 N to push a desk 10 m.

B 100


This

200 J

B 100


This

You move a wheelbarrow

50 m by exerting 100 N.

B 200


This

5,000 J

B 200


This

What is the MA of a machine that has an output of 250 J if you have an input of 10 J.

B 300


This

25

B 300


This

You push a car 0 m with 200 N

B 400


This

No work is being done because the car didn’t move

B 400


This

You carry your cat 50 m with 100 N

B 500


This

No work is being done, you are holding the cat up and moving it forward

B 500


This

What is a term that means the same thing as input force?

C 100


This

Effort

C 100


This

OL-What is the ideal mechanical efficiency of a machine?

AD- How do you calculate the mechanical efficiency of a machine?

C 200


This

OL-100%

AD- output force

input force

x 100%

C 200


This

How do you find the MA of a machine?

C 300


This

Output force

Input force

C 300


This

What are the 3 ways a machine can help you do work?

C 400


This

  • Multiply distance

  • Multiply force

  • Change direction

C 400


This

What is the MA of a machine that multiplies force?

C 500


This

Greater than 1

E 400


This

2nd class

E 400


This

What class of lever do pliers belong to?

E 500


This

F 100


This

What is used to measure how much matter an object contains?

F 200


This

Mass
