Acceleration is a change in velocity with respect to time. Velocity is a vector quantity, meaning it has both a direction and a speed. Acceleration is therefore also a vector quantity. So if you change the direction an object is moving without changing its speed, you are still accelerating the object.

The best example of this is circular motion. If you tie a string to a rock and swing around your head at a steady rate, the speed of the rock stays the same but its direction is continually changing. It is accelerating, and the acceleration vector points directly to the center of rotation.

What is the formula of accelation?

The formula for acceleration is acceleration = change in velocity / time taken. It is typically represented as a = Δv / t, where "a" is acceleration, "Δv" is the change in velocity, and "t" is the time taken.


What formula is used to calculate accelation?

Change in velocity / time


What is the formula you use to determine the accelation of an object moving in straight line?

Change in velocity over the change in time


What is a change in velocity due to a in direction or speed?

A change in velocity due to a change in direction can occur when an object changes its direction of motion, even if its speed remains constant. A change in velocity due to a change in speed occurs when an object either accelerates or decelerates, resulting in a change in its speed.


When an object turn's around or reverses direction in its motion what happens?

When an object changes direction in its motion, its velocity changes, and if the object is accelerating, its acceleration will also change direction. This change in direction is due to the application of a force in the opposite direction. The object's kinetic energy may also change as a result of this change in direction.


What is changed to cause refraction?

Refraction is a change in direction of a wave due to a change in its transmission medium.


Is acceleration due to change in direction?

Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.


Why will momentum change?

Momentum will change if there is a force acting on an object. This change in momentum can occur due to accelerations, decelerations, changes in direction, or interactions with other objects. The magnitude and direction of the momentum change depend on the strength and direction of the force applied.


What causes a spaceshuttle to change in velocity by change in direction?

A change in velocity due to a change in direction in a space shuttle is caused by the application of thrust from its engines. By adjusting the direction of thrust, the shuttle can alter its velocity vector, changing its speed and/or direction of travel. This allows the shuttle to adjust its course, orbit, or perform maneuvers in space.


Can direction of velocity of a body change when its acceleration is constant?

Yes, the direction of velocity of a body can change even when its acceleration is constant. This can happen if the acceleration and initial velocity of the body are not aligned in the same direction. The body will still experience a change in velocity due to the constant acceleration, which can lead to a change in direction.


When light waves slow down do they change direction?

When light waves slow down as they travel from one medium to another, such as from air to glass, they do change direction. This change in direction is called refraction and occurs due to the change in speed of the light waves in the new medium.


What is constant acceleration due to only a change in direction?

Constant acceleration due to only a change in direction is known as centripetal acceleration. This acceleration always acts towards the center of the circular path and is responsible for keeping an object moving in a circular motion. It does not change the speed of the object, but only the direction of its velocity.
