force Test Physical science

a man weighing 800 N is standing on a chair. in order to support the man, what force is the chair exerting

800 N up

according to newtons laws, for any object, the greater the force that's applied to it, the greater it__________will be

Acceleration

as the mass of an object increases, its inertia will______________

Increase

the_________of an object does not change, but its__________can, based on location

Mass, weight

the relationship among mass, force, and acceleration is explained by

Newtons' 2nd law

A fire fighter feels the hose pushing backwards onto him as he uses it to put out a fire. what is the Most likely cause of this?

The escaping water exerts an equal and opposite force on the hose

the upward force on a falling object through air is

air resistance

A group of students is playing tug-of-war. The students on both sides of the rope are pulling with equal force so that the rope is not moving. This is an example of.

balanced forces

the size of the gravitational force between two objects depends on their

masses and the distance between them

to every action there is an equal and opposite reaction describe law

newton's 3rd law

an astronaut is planning a trip to a newly-discovered planet. according to the law of universal gravitation, the astronauts weight on the new planet will be greater than his weight on earth if

the new planet has more gravity than earth

A student drops a feather and a rock at the same time from Mrs. Taylor's window. If air resistance wasn't a factor, what should she observe

the rock and the feather fall at the same time

describe how a swimmer moves through water

the swimmer pushes backwards on he water and the water pushes with an equal but opposite force back on the swimmer

what is measured in newtons

weight
