When the object is constantly moving, like the earth
100
What is a force?
What is a push or pull
100
How many laws of motion are there?
Three
100
Who created the three laws of motion?
Newton
100
What is direction?
The way a force is moving.
200
What is an example of variable motion?
Cars or people moving.
200
Give an example of a force.
Answers will vary
200
What is the principal from the first law that says an object can resist a change in motion?
Inertia
200
What is magnitude?
How strong a force is
200
What is an example of a constant force?
Gravity
300
Give an example of an object with periodic motion.
A pendulum

Two people are pushing a box against each other. How can they get the box to move?
One person needs to push it stronger, or with greater force, than the other
300
Give an example of Newton's first law of motion.
Answers will vary.

How quickly something can gain speed or move faster is called...
acceleration
300
How does electricity work?
A electrical force pushes or pulls on an object and the objects gain or lose electrons.
400
Which type of motion describes a ferris wheel?
circular
400
Which takes more power- running up a hill or walking up a hill?
Running up the hill
400
What is Newton's second law of motion. Give an example of it and explain what the law is.
Something with a greater mass takes more time to gain speed, or accelerate. It takes a greater amount of force to move an object with a heavier mass. Ex: shopping cart that is full is harder to move than an empty shopping cart.
400
What is equilibrium?
When all of the forces acting on an object are balanced.
400
What are three different types of forces?
magnetism, electricity, friction, gravity
500
List the five different types of motion.
Constant, variable, periodic, vibrational, and circular
500
If three people are pushing a box together, what is the net force?
The force of all three of them pushing together.
500
Describe Newton's Third Law of Motion and give an example of how it works.
Every action has a reaction- When you put a force on an object, there is going to be a reaction. Ex: bumper cars colliding, tossing a ball into the air
500
Define work.
A force moving an object.

Explain why it is easier to move across a floor wearing only socks than it is when wearing shoes.
Your shoes create friction and make it harder to move.
