The amount of matter in an object
What is mass
100
the distance traveled divided by the time interval during which the motion had occurred.
What is speed?
100
When objects change in position relative to a reference point
What is motion
100
A force that opposes motion between two surfaces in contact
What is friction?
100
What is gravity
A force of attraction between objects that is due to their masses

I am related to mass but not the same. I change when the gravitational force changes. What am I?
What is weight?
200
The speed of any instant time is known as
What is instantaneous speed?

Which is an example of static friction?
a. Rubbing a ball on your head b. Pushing a washing machine across the floor c. Punching a pillow d. Stomping your feet.

Why are mass and weight often confused?
Answer: Mass and weight are often confused because they both are constant on Earth and because the terms mass and weight are sometimes used to mean the same thing.

Name two ways that friction is harmful and helpful and two ways friction is helpful to you when you ride a bicycle
Answer:Friction is harmful because it causes tire tread to wear down and causes the brakes to wear down. Friction is helpful because it helps the wheels grip the road and helps your feet and hands stay on the pedals and handlebars

Explain why it is your weight and not your mass that would change if you landed on Mars?
Answer: Your weight would change if you landed on Mars because the gravitational force on Mars is different from the gravitational force on Earth. But your mass would not change because the amount of matter in your body would not change.
