# FAQ: When A Car Goes Around A Circular Curve On A Horizontal Road At Constant Speed, What Force?

## When a car goes around a circular curve on a horizontal road at constant speed?

Terms in this set (58) When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path? d. No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.

## When a car goes around a circular curve on a horizontal road at constant speed what force causes it to follow the circular path when a car goes around a circular curve on a horizontal road at constant speed what force causes it to follow the circular path?

Figure 6.21 This car on level ground is moving away and turning to the left. 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.

## When a car goes around a circular curve on a horizontal road at constant speed what force causes it to follow the circular path when a car goes around a circular curve on a horizontal road at constant speed what force causes it to follow the circular path the normal force from the road gravity?

Figure 1. The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve.

## When a planet goes around a circular orbit at constant speed what force causes it to follow the circular path?

A body in uniform circular motion undergoes at all times a centripetal acceleration given by equation (40). According to Newton’s second law, a force is required to produce this acceleration. In the case of an orbiting planet, the force is gravity.

## How does centripetal force affect circular motion?

As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.

## Which force is responsible for holding a car in an unbanked curve?

When a car moves at a steady speed around an unbanked curve, the centripetal force keeping it on the curve comes from the static friction between its tires and the road.

## What force causes it to follow the circular path?

A centripetal force is a net force that acts on an object to keep it moving along a circular path.

## What is the direction of centripetal force when particle is following a circular path?

What is the direction of centripetal force when particle is following a circular path? CLASS – XI PHYSICS (Kinematics) if the particle is moving in the circuilar path, then the direction of centripetal force is towards the centre of the circle or along the radius of the circle.

## How does the force of gravity change if the distance between two objects triples?

If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

## How do you find centripetal acceleration without radius?

To calculate centripetal force without a radius, you need either more information ( the circumference of the circle related to radius by ​C​ = 2π​r,​ for example) or the value for the centripetal acceleration.

## Why are circular orbits rare in the galaxy?

To get a perfectly circular orbit of a certain radius requires the planet to have a certain velocity, which is extremely unlikely. Any deviation from that velocity will result in an elliptical orbit (up to the limit when the planet is travelling so fast it escapes).

## What keeps a satellite moving in a circular motion?

An object will only accelerate if a resultant force acts on it. For an object moving in a circle, this resultant force is the centripetal force that acts towards the middle of the circle. Gravitational attraction provides the centripetal force needed to keep planets and all types of satellite in orbit.

## Why does the force of gravity do no work on a satellite in circular orbit?

The force of gravity does no work on a satellite in circular orbit since the force is always perpendicular to the planet’s direction of motion. The gravitational force does do work on a satellite in elliptical orbit because there is a component of the force in the direction the satellite moves.
