# Often asked: When A Car Turns A Corner On A Level Road?

## When a car turns a corner on a level road which force provides the necessary?

5) Friction. Explanation: The force that provides the necessary centripetal acceleration is the friction. The centripetal acceleration must be horizontal, directed to the center of the circular trajectory.

## When a car turns a corner on a level road which force provides the necessary centripetal acceleration when a car turns a corner on a level road which force provides the necessary centripetal acceleration tension air resistance gravity normal force friction?

Three such examples of centripetal force are shown below. As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion.

## Would you consider a car turning around a corner at a constant speed to be 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.

## When a car around the 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.

## When a ball on the end of a string is swung in a uniform horizontal circle the ball is accelerating because?

The forces on the ball are gravity and the tension in the string. The tension in the string is directed along the string and the gravity force is straight downward. The free-body diagram for the moving ball is given in Figure 4. Since the ball moves in a horizontal circle, its acceleration is horizontal.

## Why is it called uniform circular motion?

Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction.

## 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.

## Why is centripetal acceleration always towards the center?

Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration. The acceleration is directed radially toward the centre of the circle.

## 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.

## Can u go around a curve with constant acceleration?

Can you go around a curve with constant acceleration? No, because the vector always points to the center of the circle and you are always changing the direction of that vector.

## Can a body have uniform speed but still have acceleration?

Since speed is equal to the magnitude of the velocity vector, it will also be constant. Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the acceleration of the body will be zero. Hence, a body can have a constant speed and still be accelerating.

## Does a positive acceleration always mean an object is speeding up?

An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. If acceleration points in the same direction as the velocity, the object will be speeding up.

## When a car goes around the corner at 20 miles per hour Why do we say it accelerates?

The car is accelerating because it’s changing direction. When a car goes around a corner at 20 mph, why do we say it accelerates? When something changes position or moves.
