All Flashcards
What is the effect of the net force pointing towards the center of the circle?
The object moves in a circular path.
What happens when the speed of an object in circular motion is doubled?
The centripetal force required to maintain the same radius is quadrupled.
What is the effect of gravity acting as the centripetal force for a planet's orbit?
The planet orbits the star (e.g., the sun).
What is a Free Body Diagram (FBD)?
A visual tool showing all forces acting on an object.
What is centripetal force?
The net force that always points towards the center of the circle, causing an object to move in a circular path.
Define normal force.
The force exerted by a surface on an object, often perpendicular to the surface.
What is apparent weight?
How heavy you feel, which is related to the normal force acting on you.
Define weight force (W).
The force of gravity on an object, acting at the center of mass, pointing downwards towards the Earth.

What is centripetal force?
The net force that points towards the center of the circle, causing an object to move in a circular path.
Define normal force.
The force exerted by a surface on an object in contact with it, usually perpendicular to the surface.
What is apparent weight?
How heavy you 'feel', which is related to the normal force acting on you.
Define weight force.
The force of gravity acting on an object, always pointing downwards towards the Earth.
