Forces and Motion Quizizz

1) You are in a car seeing yourself go by a cow grazing in the field. For you that cow is a _____________ point.

• reference
• force
• motion

2) Any push or pull on an object is ______________.

• force
• friction
• speed

3) If you are pushing a box on a surface with more friction, you would expect to have to apply __________ force to move the object.

• equal
• less
• more

4) Chase runs 100 meters in 11.3 seconds while Hailey runs 100 meters in 11.8 seconds. Who has a greater speed?

• Hailey
• Chase
• They both have the same speed.

5) What is the difference between speed and velocity?

• Speed is only how fast something is going while velocity is both how fast and in what direction.
• Speed uses distance divided by time while you need the initial and final speed to calculate velocity.
• There is no difference between speed and velocity. They both are how fast something is going.

7) Which best describes what it means to have "negative acceleration"?

• An object is slowing down.
• The object is going backwards as it is accelerating.
• The object is accelerating in a zero gravity environment.

8) The correct label for force in the metric system is ____________.

• Newtons
• meters per second squared
• pounds

9) A system that uses background objects to establish position or to measure movement in space is known as _____________________.

• acceleration
• a frame of reference
• kinetic energy
• potential energy

10) Which of the following would represent BALANCED forces?

• Two people are arm wrestling, but their arms aren't able to move each other.
