how many forces must be applied to make a simple machine work?

three

two

one

four

the rate at which an object moves

distance

mass

force

speed

a simple machine with a sloped side

inclined plane

screw

wedge

lever

a wedge is a simple machine that makes work easier by

holding things up

pushing material outward

lifting things

turning things

the use of force to move an object is

gravity

force

work

friction

the girl is pushing a box up a ramp. How would the motion change if the girl used a greater force in the same direction

the mass of the box would decrease

the box would stop moving

the direction of motion would change

the speed of the box would increase

a force of attraction between two objects even if they are not touching

gravity

friction

balanced forces

work

which object will require the most force to toss it 3 feet

plastic disk

tiny metal screw bolt

small wooden block

balanced force

the amount of gravity pulling down on an object

volume

mass

weight

force

which would be the best simple machine to use to slice onions
