A student drops a feather and a rock at the same time form Mrs.Artrip's window. if air resistance wasn't a factor, what should be observe,

The rock falls faster than the feather

Which is the following best describes how a swimmer moves through the water?

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

According to newton's laws for any object, the greater the force that applied to it, the greater it's what will be

acceleration

the upward forces on an object falling through the air

air resistance

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

balanced forces

when two forces on the same object, are equal and opposite, these forces are called

balanced forces

as the mass of an object increases, it''s intertia will

increase

How does gravitational force change as two objects mover farther apart?

it decreases?

the blank of an object does not change, but it's what can be on its location

mass, weight,

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

masses and distance between them

an object accelerates in the same direction as which of the following

net force

a firefighter feels the hose psuhing backwards onto him as he used it to put out a fire. what is mostly likely cause of this?

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

Which explains why astronauts seem weigthless in orbit?

the spacecraft in free fall

which two quantities are measured in the same units?

weight and force
