# Question: What Force Accelerates A Car Driving A Circular Path On A Flat (level) Road At A Constant Speed?

## What forces are active when a car is accelerating on a flat road?

When the car accelerates, there is a horizontal forward force on the car, and a corresponding backwards horizontal force on the ground. As the car picks up speed, air resistance produces a backwards force.

## What causes centripetal acceleration?

Centripetal forces cause centripetal accelerations. In the special case of the Earth’s circular motion around the Sun – or any satellite’s circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.

## Which force is responsible for keeping a car moving in a circular path at constant speed on 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.

## How does centripetal force cause circular motion?

An object is in circular motion. It would move in a line tangent to the circular path. A centripetal force causes circular motion because it accelerates an object. toward the center of a circle, which changes the direction of motion but not the speed.

## What is the force that moves the car?

Friction is a force that arises when things rub together. The frictional force between the road and tire is what allows the tire to “push” off the road, thus moving the car forward (Newton’s third law — the action is the pushing frictional force, the reaction is the forward movement of the car).

## What are 3 examples of centripetal force?

Just a few examples are the tension in the rope on a tether ball, the force of Earth’s gravity on the Moon, friction between roller skates and a rink floor, a banked roadway’s force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.

## What is tangential acceleration formula?

The tangential acceleration = radius of the rotation * its angular acceleration. It is always measured in radian per second square. Its dimensional formula is [T2]. When an object makes a circular motion, it experiences both tangential and centripetal acceleration.

## When a car rounds a corner at a constant speed its acceleration is zero?

An object at rest will remain at rest, and a moving object will remain at a constant velocity unless unbalanced forces act on it. For every action, there is an equal and opposite reaction. The SI unit of acceleration is meters per second. When a car rounds a corner at a constant speed, its acceleration is zero.

## Is it possible for a vehicle to travel around a curve without accelerating?

Explanation: An acceleration is necessary for an object to change direction. The car experiences a centripetal force as it turns the corner as a result of friction. The magnitude of the velocity does not change, but the direction does.

## What is the maximum speed the car can travel around the curve without slipping?

The maximum velocity for the car is about 12 m/s.

## At what maximum speed can the car navigate the curve?

The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.85 on the same curve.

## Is tension a centripetal force?

A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal forces.

## What is the time for one lap around a circle called?

The time for one revolution around the circle is referred to as the period and denoted by the symbol T.
