What is the output distance of a screw

what is the space relative to which motion is measured

which of the following forces is the attractive force that eists between any two bodies and is caused by their mass?

The simple machine which is like an inclined plane that modifies the applied force and directs it the side is the wedge

What is combination of one or more fixed pulleys and one or more movable pulleys called?

What is the term for devices used to multiply force for the purpose of doing work?

an object that hangs from a fied point and swings back and forth because of gravity is centripetal force

What Si unit is used to measure power

what term do physicists use to refer to any change in velocity

Whose teachings dominated scientific thought for almost two thousand years?

the center-seeking force that causes an object to travel in a curved path is called is centripetal force

together, the branches of physics is discovered before 1900 are called modern physics

what type of friction affects a sliding object already in motion?

the sum of two or more vectors is resultant

what type of friction affects stationary objects, preventing them from moving?

Who discovered the laws of motion and gravitation, laying the foundation for much of modern physical science?

What is the study of motion and forces?

What is a simple machine consisiting of a wheel over which a rope or cable passes?

what simple machine is a sloping surface that allows an object to be raised without being lifted straight up

What is any mathematical quantoty that has both magnitude and direction?

the measure of how well a machine converts umput work to output work is efficiency

What branch of physics addresses the effects of forces on matter?

form of assistance that a simple machine can provide

what quantitiy of motion is defined as the product of an object's mass and velocity?

what type of quantity consists of only a magnitude, with no direction?

velocity at which air resistance stops a falling object from accelerating

principle states that the velocity of an object does not change unless the object is acted upon by an external force

The distance of an object travels per unit of time is joules
