4. Can you go around a curve with constant acceleration? Explain 6. If you whirl a yo-yo about your head in a horizontal circle, in what direction must a force act on the yo-yo? What exerts the force? 7. You swing a yo-yo about your head in a horizontal circle, then you swing another one with twice the mass, but you don't change the length of the string or the period. How do the tensions in the strings differ? 8. A 2500 kg car enters a curve with a radius of 45 m. If the car is moving at a speed of 35 m/s, what is the centripetal force that maintains the car's circular motion through the curve?

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.
