Uniform Circular Motion
The motion of an object in a circle with a constant speed and a constant radius.
Period (T)
The time it takes for one complete revolution of an object in circular motion.
Centripetal Force
The force required to make an object move in a circular path, directed towards the center of the circle.
Centripetal Acceleration
The acceleration of an object moving in a circle, directed towards the center of the circle.
Tangential Velocity
The velocity of an object moving along the edge of a circular path, tangent to the circle.
Free Body Diagram (FBD)
A diagram that shows all the forces acting on an object.
Normal Force (FN)
The force exerted by a surface to support the weight of an object resting on it.
Friction Force
The force that opposes the motion of an object and acts parallel to the surface.
Gravitational Constant (G)
The constant used in the equation of gravitational attraction, approximately 6.67 imes 10^{-11} ext{ N} ext{m}^2/ ext{kg}^2.
Newton’s Law of Universal Gravitation
The law that states that every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
