What does a stopwatch do?

It measures time. (how long or how fast something takes)

100

What is the definition of Gravity

force that pulls

100

*Double Points* What is work?

When there is force and motion

200

What does M.E.L.T.S mean?

Mechanical, Electrical, Light, Thermal, and Sound Energy

200

Which simple machine did we use in our car lab?

Wheel and Axle


200

What is a spring scale?

Something that weighs things or Measures how much force is needed to move an object
200
Does Gravity Slow the toy car down or speed it up?

Speed it up

Give an example of work being done, and tell me why?

I'll say if its correct or not

300

Thermal/Solar/Light


300

What is a fulcrum?

it helps lift a heavy load, stays in place
300

*Double Points*


Draw how friction works

I'll say yes or no

300

What is a surface and why does it matter?

I'll say if correct

400

Electrical


400

Which type of simple machine do the curtains in Mr. Delgado's class use?

Pulley

400

*DOUBLE* 

When using a spring scale, why would i need to use a lot of force one time, and then a little bit of force the next time? If the weight of the object was the same for both, what changed?

The surface. A rougher/bumpy surface would cause more friction. More friction requires more force.

400

Draw how the car lab worked. Draw the car/materials and how it worked.

I'll check

400

When doing an experiment, why is it important to do multiple trials. (test it out more than once)

to make sure that you are getting a true/accurate result.

500

Solar energy from the sun is then transferred to what?

Electrical Energy for an object to use

500

Explain a wedge and how it works

I'll say whether correct or not

500

If i'm measuring 10 different rubber bands, all shapes, and all sizes. I want to see which one is more durable. I attach weights to each rubber band. What needs to be true, to make the experiment valid?

All the weights need to be the same weight.

500

If one student pulls a car to the right, which direction would the the other student need to push in order for the car to move forward?

Right
