What is centripetal acceleration?
A particle or object rotating in a circular orbit has an acceleration directed towards the center. This is called centripetal acceleration.
A particle or object rotating in a circular orbit has an acceleration directed towards the center. This is called centripetal acceleration.
See lessWhat is centripetal force?
Centripetal force is a force acting towards the center of a circle to keep an object moving in a circular path.

Angular momentum is the vector product of the position vector of a moving object (i.e., the distance from the axis of rotation) and the linear momentum of the object.

See lessWhat is the illusion of inertia?
The moment of inertia is the sum of the product of the mass of each particle of a solid rotating about a fixed axis and the square of the distance of each particle from the axis of rotation.

The ratio of the value of the boundary friction force acting between two surfaces in contact and the perpendicular reaction is called the coefficient of friction.
See lessExplain friction force.
Friction force is the resisting force due to friction when an object tries to move or moves over another object. It acts along the tangent of the contact surface of the objects in the opposite direction of motion.

If two or more forces act on an object at the same time, and the object remains at rest (i.e., the magnitude of the force applied on the object is zero), then the force is said to be in equilibrium.
