If a ramp is steeper, having a larger theta, then the object rolling down it will become faster. However, if the object is rolling up the ramp, will it slow down? How can I prove this?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
