What increases the centripetal force?

Like other forces , centripetal force is also mass times the acceleration. However here the acceleration is centripetal acceleration . Thus Centripetal force can be increased , by increasing the mass , increasing the centripetal acceleration or by increasing both the mass and centripetal acceleration.

What happens to centripetal force as radius increases?

Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the F c , the smaller the radius of curvature r and the sharper the curve. The second curve has the same v, but a larger F c produces a smaller r′.

Does centripetal force increase with speed?

Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.

How do you increase centripetal acceleration?

If you are keeping the angular speed constant (which is the same as keeping the frequency of revolution or the period constant) then the centripetal acceleration would increase. An example of this would be moving away from the centre of a rotating carousel.

What generates centripetal force in a vehicle?

The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road. A minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway.

How does radius effect circular motion?

The greater the speed, the greater the radial acceleration. A particle moving at higher speed will need a greater radial force to change direction and vice-versa when the radius of the circular path is constant.

Does increase radius increases centripetal acceleration?

Where is the centripetal acceleration on an object, is the velocity of an object, and is the radius in which the object moves in a circle. The radius has an inverse relationship with centripetal acceleration, so when the radius is halved, the centripetal acceleration is doubled.

What affects centripetal force the most?

Three factors which affect the centripetal force are:

• mass of the object;
• its speed;
• the radius of the circle.

What is the magnitude of the centripetal force?

The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion, for every action there is an equal and opposite reaction.
