## What is perpendicular acceleration?

Acceleration that is perpendicular to velocity changes ONLY the velocity’s direction. The speed remains unchanged, only the direction of velocity. The perpendicular (or normal) acceleration changes the trajectory, and that is all.

**Which of the following scenarios the acceleration acting on the object will be perpendicular to the velocity?**

(c) an object moving in a certain direction with an acceleration in the perpendicular direction. Answer : (a) It is possible; an object thrown up into the air has a constant acceleration due to gravity acting on it. However, when it reaches its maximum height, its velocity is zero.

### Does direction of acceleration indicate the direction an object is moving?

Keep in mind that although acceleration is in the direction of the change in velocity, it is not always in the direction of motion. When an object slows down, its acceleration is opposite to the direction of its motion. This is known as deceleration.

**What is the direction of acceleration of an object is moving to the right and slowing down?**

If an object is moving to the right and slowing down, then the net force on the object is directed towards the left. Accelerating objects are either slowing down or speeding up. An object has an acceleration of 8 m/s/s.

## Why is the direction of centripetal acceleration always perpendicular to the velocity?

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. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.

**Is it possible for an object moving around a circular path to have an acceleration that is not perpendicular to velocity?**

In physics, when an object travels in uniform circular motion, its speed is constant, which means that the magnitude of the object’s velocity doesn’t change. Therefore, acceleration can have no component in the same direction as the velocity; if it did, the velocity’s magnitude would change.

### What direction do objects accelerate?

In each case, the acceleration of the object is in the positive direction. In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity.

**Can an object moving with an acceleration but with uniform speed?**

Answer: It is possible. Explanation: If a body moves in a circular path, then it has constant speed but due to constant change in direction, velocity changes and the motion is accelerated.

## Is the car accelerating if so what is the direction of acceleration?

Acceleration has direction, just like velocity. In the figure below, both cars are accelerating because their speeds are changing. When a car’s acceleration and velocity are in the same direction, the speed increases and the acceleration is positive.

**In what way is an object moving in a circle always accelerating?**

Objects moving in circles at a constant speed accelerate towards the center of the circle. The acceleration of an object is often measured using a device known as an accelerometer.

### Is the acceleration of the body perpendicular to the direction?

The acceleration of the body is along the radius, while the direction of the body is along the tangent. Radius is perpendicular to tangent. Thus, acceleration is perpendicular to the direction.

**When is an object moving along a circular motion?**

When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius. We understand that with the radius, a tangent still makes a right angle.

## Is it possible for an object to move in a certain direction?

An object moving in a certain direction with acceleration in the perpendicular direction. Is this situation possible? Give an example of such situation. Yes, The above given condition is possible. e.g.

**Can you give an example of acceleration in a direction?**

Give an example of such situation. Yes, The above given condition is possible. e.g. When a stone tied to a string is whirled in a circular path, the acceleration acting on it is always at right angle to the direction of motion of stone. This video describes the numerical based on first equation of motion.
