a push or a pull is known as what?
What is force?
and object at rest will remain at rest, and an object in moyion will intend to stay in motion unless an outside net force is acted upon it
What is newtons first law?
What is the formula for Newton's 2nd law
f =m*a
what does Newton's 3rd law state?
What is for every action there is an equal and opposite reaction?
what happens when there is a balanced force on an object
all the sum of forces acted upon an object
What is net force?
when the net force is 0 and the forces cancel each other out
What is balanced forces
Explain the action reaction pairs in a rocket
What is jet fuel pushes down (action) air pushes rocket up (reaction)
what is the unit of mass, force, and acceleration?
What is kilogram, newton, and m/s/s?
when an object is caused to move in a circular motion at a constant speed
What is centripital force?
when the net force is greater than 0 and the forces do not cancel each other out
What is an unbalanced force?
when an object speeds up, slows down or changes direction.
What is acceleration?
the forces exerted by two objects on each other
What is action reaction pairs
