REVIEW 6

if the MA is equal to 5 and the distance is 5m, then what is the effort distance?

• 1 m

• 0 m

• 25 m

• 10m

is the forces are zero then an object will...

• stop

• move at constant velocity

• accelerate

• nothing

if you have 10 N on a box and it is pushed 5 m across the floor, then what is the work being done?

• 4 J

• 5 J

• 15 J

• 50 J

if a box that weighs 80kg needs to be pushed with a force of 100 N, what is the acceleration?

• 1.25 m/s2

• 80 m/s2

• 1.5 m/s2

• 2o m/s2

if you travel from 30 mps to 60 mps in 6 seconds, then what is the acceleration?

• 33 m/s

• 5 m/s

• 10 m/s

• 5 m/s

if 2 boxes are dropped in a vacuum at the same height but different weights then...

• both fall at constant speed

• both accelerate at the same rate

• accelerate at different rate

• speed up at different times

if you have a force pushing on the right side of a box at 50 N towards the left and another force pushing on the left side of the box at 30 N to the right, then what will happen?

• will not move

• move to the left at constant speed

• move to the right at increasing speed

• move the left at increasing speed

which is an example of Newtons 1st law

• shopping cart getting heavy

• your body moving forward when a car stops

• running

• hitting a football player

What type of force is the difference between mass and weight? (think earth)

• magentic

• Oceanian

• friction

• gravitational

Which is an example of Newtons 3rd Law

• rocket taking off

• pushing a shopping cart

• the acceleration felt in a car

• waves hitting a boat
