Question

Derive an expression for linear acceleration of a particle performing u.C.M

Answer 1

Hey dear,

[Refer to the image attached for derivation of linear acceleration.]

◆ Linear acceleration -
- In non-uniform circular motion, acceleration has two components.
1. Centripetal acceleration
2. Tangential acceleration
- These two components of acceleration are perpendicular to each other.

# Centripetal acceleration -
- It's direction is along the radius of circle and magnitude is given by -
ac = v^2/r


# Tangential acceleration -
- It's direction is along tangent to a point on circle and magnitude is given by -
at = rα
