C

centripetal

the inward force that acts on an object moving in a curved path, pulling it towards the center of the curve. It's like a cosmic hug, ensuring that objects stay on their graceful trajectories and don't wander off into the cosmic abyss. It can be calculated using the equation F = \( \frac{mv^2}{r} \). where m represents the mass of the object, v represents its linear velocity, and r represents the radius of the curved path.

Centripetal acceleration

Acceleration directed toward the centre of a circular path.

Centripetal force

The resultant inward force responsible for centripetal acceleration.

Circular motion

Motion along a circular path.

coefficient of friction

often denoted by the Greek letter "μ" (mu). It has two distinct forms: static (μs), which describes the resistance to motion between stationary surfaces, and kinetic (μk), which describes the resistance to motion between surfaces in relative motion.

Collision

An interaction in which objects exert forces on each other over a short time.

Component

One part of a vector acting in a particular direction.

Connected objects

Objects whose motions are linked by a string, rope, cable, or other connection.

Conservation of momentum

The principle that total momentum remains constant in an isolated system.

Contact force

A force that acts only when two objects are touching.
