What factors determine what an objects momentum is
When the mover pushes the box up the ramp there is friction between the box and the ramp What is the efficiency of the ramp
It depends on the mass of the box, the force exerted, the total
displacement and the height the box was moved.
Does the Universal Law of Gravitation say that any two objects in the universe will exert a gravitational force on each other
A chisel is an example of what kind of simple machine
What factor of both the wheel and axle can be used to calculate their mechanical advantage
A force can be a push or a pull that if unbalanced can cause a change in an object's motion
On a spinning ride at the fair it is inertia that keeps you moving in a circle
Gravity provides a centripetal force on the Moon helping it stay in orbit around Earth
Gravity provides a centripetal force on the Moon, helping it
stay in orbit around Earth.
TRUE!!!

When a car turns a corner causes its passengers to feel like they are being pushed away from the direction of the turn
The fact that the sun exerts a force on you even though it is very far away is a consequence of the Universal Law of
Gravitation

Newton's laws of motion are all about what
Newton's laws of motion are about motion.
How much force will it take to accelerate a 900-kg car at 6 ms2
Rearrange F equals ma
F = MA
M = F / A
A = F / M
What force do the brakes use to stop a car
the brakes use friction to stop the car
Does speed affect gravitational potential energy of an object
Does speed 'effect' the gravitational potential energy of an
object? No, but gravitational potential energy can be converted
into kinetic energy - so the gravitational potential energy can
effect the speed.
Ep = mgh
Energy Potential = mass * 9.81 (gravity) * height
Speed / Velocity is absent from that equation.
What force caused the brakes on the car to slow you down
What kind of screw can you put in a tree
Since tree trunks are made of wood, you can put a wood screw
into them if you wish. It is always easier to screw in a screw if
you drill a guide hole first.
What statement best describes what happened to the groups on separate reservations
They became culturally different from one another.
