Which is not a simple machine

• tractor
• ramp
• wedge
• screw

if a car is not speeding up or slowing down it has

• constant velocity
• positive velocity
• negative velocity
• no velocity

Maicie is running at 12 mph/n which would not be a change in acceleration

• 12 mph/e
• 12 mph/w
• 12 mph/s
• 12 mph/n

why do you increase the distance of a inclined plane?

• it reduces work
• it reduces effort force
• it increases effort force

why do you increase the distance of a inclined plane?

• it reduces work
• it reduces effort force
• it increases effort force

20 n→ ←15 n what will happen?

• nothing
• accelerate to the right with 5n
• accelerate left with 5n
• forces will cancel out

⁄  this would be an example of what type of acceleration?

• positive
• negative
• constant
• none

−−−−−−−− what type of acceleration would this represent

• positive
• negative
• constant
• none

−−−−−− what type of velocity 

• positive
• constant
• negative 
• none

which object would accelerate the most with 200 n applied to it

• 10 kg
• 12 kg
• 15 kg
• 100 kg
