What three forces cause an object to change its motion?
The three forces that causes an object to change its motion are the gravitational force, the normal force and the frictional force.
What two things should you describe about a force that acts on an object?
the 2 things you should describe about a force that acts on an object is the size and direction
Three things that can be acceleration?
Only one thing can be acceleration; the changing velocity of any given object. That's what acceleration is. Acceleration is caused by a net force on the object.
What two things you do that use force?
pushing an object. pulling an object
If rotation of an object causes centrifugal force which pulls things outward why does a vortex pull things inward?
Centrifugal force doesn't exist, and no outward-pulling force is caused by rotating an object.

What are the three forces can cause an object to change?
the answer is frictional force elotromagnetic force gravitational force
What two things can set a still object in motion?
Only force can. But there must be a million things that can produce the force, including everything from golf clubs to rocket engines.
What is gravitition force?
A force generated b every object with mass that pulls things towards it. The bigger the mass of an object the bigger the gravitational force.
What three things can happen to an object if the forces acting on it are unabalanced?
it will become unballanced it will push the side that has the most force on it down it will become unstable
What 2 things affect the acceleration of an object?
-- the object's mass -- the net force acting on it
What two things affect the gravitational force acting on an object?
The mass of the object that is exerting the force and the distance between the two objects.
What is the force that causes things to move in space?
A force can cause an object to move if the amount of the force in the direction of movement is larger than the Frictional force of the object against the object on which it rests, and can overcome its Inertia.
