What direction does a centripetal force act?
radially inward
Explain why an object in orbit needs a centripetal force acting on it in what direction does a centripetal force act?
1). If there is no force on the object, then it keeps moving in a straight line. If you want it's path to bend away from a straight line, then you need a force in order to accomplish that. 2). The force acts in the direction that bends the path away from a straight line. In other words, in the direction in which the path curves. For a closed orbit, the force has to be toward the center, or at least close to it. Conveniently, that's where the big massive body happens to be, which sets up a nice, two-way gravitational force between the central body and the orbiting body. Gravity is the centripetal force, and it always points both ways between the two bodies, trying to draw them together.
What happens when a net unbalanced force act on an object?
Moves it the opposite direction.
What happens when 2 forces act on an object in oppposite directions?
The object accelerates in the direction of the force difference.
What is the force that atcs in an opposite direction to the motion of a moving object?
Friction always acts in a direction opposing the motion of an object.
What force keeps an object moving in a cyrcle and in what direction does this force act?
Centripetal Force, it always points to the center of the circle.
What force keeps an object moving in a circle. in what direction does this force act?
The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle
What direction does a centripetal force act?
radially inward
What kinds of forces can act on an object?
Normal force can act on an object
How does the centripetal force act on a satellite?
Centripetal force makes a satellite orbit a body.
How do you find the net force when two forces act the same direction?
If many forces act in the same direction on an object, then the net force is their sum.

Can a net force act on an object and not cause it to change speed or direction?
No.
Does the centripetal force act as an unbalanced force on the satellite in orbit?
Yes. According to Newton's Second Law, there has to be an unbalanced force - otherwise, the satellite won't accelerate (in this case, change direction).
When two forces act on an object in opposite directions and the object moves will it move in the direction of the smaller or greater force?
Greater force
What happens when a net unbalanced force act on an object?
Moves it the opposite direction.
What happens when 2 forces act on an object in oppposite directions?
The object accelerates in the direction of the force difference.
