Unit 6 Test Energy and Simple Machines

Master energy and simple machines with this engaging physics worksheet. Perfect for review!

Nonrenewable energy resources like oil and coal are ..... used slower than they are replaced used faster than they are replaced True or False? Energy cannot be destroyed or created. It can only change form or transform True False Why are simple machines useful? They are fun to use They make work more challenging They make everyday tasks easier The roller coaster cart will have the least amount of potential energy at which position? W X Y Z Name the simple machines:ball rolls down a ramp and lands on a seesaw which pushes a balloon into a nail inclined plane -> wedge wheel and axle -> inclined plane -> lever -> wedge inclined plane -> lever -> wedge inclined plane -> lever Name the simple machines:a car moves along a table and then bumps into dominoes that hit a ball which goes down a ramp lever -> inclined plane -> wedge wheel and axle -> inclined plane -> lever inclined plane -> lever -> wheel and axle wheel and axle -> lever ->inclined plane How does increasing the length of the handles on a wheelbarrow affect the amount of effort that is needed to move the wheelbarrow across the yard? it makes it easier to move the wheelbarrow it makes it harder to move the wheelbarrow If you had a project that required moving bricks from the driveway to the backyard, which type of wheelbarrow would be most helpful? A wheelbarrow with small wheels A wheelbarrow with large wheels A wheelbarrow with a large container What is the correct order of kinetic energy from least to greatest? toddler walking, plane flying, lightning striking, worm digging lightning striking, toddler walking, plane flying, worm digging worm digging, toddler walking, plane flying, lightning striking plane flying, lightning striking, worm digging, toddler walking If you are having difficulty trying to lift a refrigerator with a lever, how could you increase the mechanical advantage? find a lighter refrigerator use a longer lever use a short lever give up and take a nap Find the correct matches below Potential energy can increase when... an object is raised or moved to a higher position renewable energy source solar power nonrenewable energy source coal Kinetic energy can decrease when... an object is slowed down by friction Lever seesaw screwdriver opening a paint can effort arm, resistance arm, and fulcrum Wheel and Axle ferris wheel at the carnival merry-go-round Pulley rock climbing raising a flag on a flag pole movable fixed Inclined Plane ramp slide staircase Wedge knife door stopper nail
