Unit 3 Quizizz Review

Two factors that determine work are...

• Force

• Mass

• Velocity

• Distance

If you push a cart with a force of 60 N for 2 m... how much work have you done?

• 120 J

• 30 J

• 120 N

• 30 N

The ( ) the force the ( ) work is done

• less, more

• smaller, more

• bigger, more

• bigger, less

If the object does not move then what is happening

• nothing

• work

• power

• no work is being done on the object

what is the two things that need to occur for work to have been done?

• force and movement

• movement and direction

• constant force and power

• power and work

What is potential energy?

• The energy an object has due to its atomic structure.

• The energy an object has due to its chemical composition.

• The energy an object has due to its motion.

• The energy an object has due to its position or condition.

What is kinetic energy?

• The energy an object has due to its position or condition

• The energy an object has due to its motion

• The energy an object has due to its chemical composition

• The energy an object has due to its atomic structure

When does an object have no kinetic energy?

• When it's at rest.

• When it's moving very slowly.

• When the only force that's acting on it is gravity.

• When it has no electrical charge.

When does a yo-yo have the most potential energy?

• When it's at its highest point.

• When it's at its lowest point.

• When it's moving between its highest and lowest points.

• When it's moving at its top speed.

At which point does the ball has the greatest gravitational potential energy (GPE)?

• A

• G

• D

• C

• G
