This is an educated guess about the results of an experiment.

HYPOTHESIS

100

This word refers to how far an object has traveled

DISTANCE

100

What are the 3 ways you can have a change in velocity?

Increasing speed, decreasing speed, and change in direction

100

This is the energy an object has when it is stationary.

POTENTIAL ENERGY

100

What is the unit for force?

Newton

200

This is the variable of the experiment that you change in order to see different results.

INDEPENDENT VARIABLE

200

A car travels 50 miles in 10 minutes. What was the car's speed?

5 miles per minute

200

What is the difference between speed and velocity?

VELOCITY INCLUDES DIRECTION

200

Name one type of kinetic energy.

MECHANICAL, ELECTRICAL, SOUND, ELECTROMAGNETIC, or THERMAL

There are 2 people that are pushing and pulling a box to the left. Person 1 pushes with a force of 15 Newtons. Person 2 pulls with a force of 12 Newtons. How much force is acting upon the box and in what direction?

27 Newtons to the LEFT

300

This is the step of the scientific method where you run the tests and collect data.

EXPERIMENT

300

A horse gallops 6 miles in 1.5 hours. What was the horse speed?

4 miles per hour

300

A car travels up a hill going 40 miles per hour. Then, it travels down the hill going 75 miles per hour. What is the car's acceleration?

Increasing (speeding up) by 35 miles per hour. 

300

A ball rolling down the hill has a potential energy of 2.5 Joules and a kinetic energy of 8.5 Joules. What is the ball's mechanical energy?

11 Joules

300

There are 2 people pulling on the box in OPPOSITE directions. The person pulling to the left pulls with a force of 42 Newtons. The person pulling to the right pulls with a force of 26 Newtons. What direction is the box moving and with how much force?

16 Newtons to the left

400

This is the variable that is the result or the change in response to the independent variable.

DEPENDENT VARIABLE

400

A plane, with a speed of 300 miles per hour, travels for 3 hours. How far did it travel?

900 miles

400

A rollercoaster cart goes down a hill at 80 miles per hour. Then it travels through the loop with a speed of 65 miles per hour. What is the cart's acceleration?

Decreasing (slowing down) by 15 miles per hour. 

400
A 15 kilogram book is about to fall off a desk that is 2 meters high. What is the book's potential energy? 

294 Joules

400

What is the density of a rock that weighs 15 kilograms and has a volume of 7.5 cm3

2 kilograms per cm3

500

This is the step of the scientific method where you come up with an answer after you have analyzed the data. 

CONCLUSION
500

A dog runs down the street with a speed of 5 miles per hour. It ran a total of 15 miles. How long did the dog run for?

3 hours

500

A person running a marathon run the first 16 miles in 4 hours. Then, they run the last 10 miles in 5 hours. What is the person's acceleration?

Decreasing (slowing down) by 2 miles per hour. 

500

A rollercoaster cart that weighs 60 kilograms rolls down a hill with a speed of 30 meters per second. What is the cart's kinetic energy?

27,000 Joules

500
