velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.

Can an object moving at a constant speed have acceleration?

Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.


Can a body moving with uniform speed have variable velocity?

Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity


What describes both speed and direction?

Velocity describes both the speed and direction an object is moving.


When can an object a constant speed but not a constant velocity?

If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.


A ball is thrown vertically upward. What are its velocity and acceleration when it reaches its maximum altitude What is the acceleration of the ball just before it hits the ground?

At the maximum height the ball will be completely stopped from moving upward or downward; thus the speed of the ball would be 0 mph. The ball is only stopped for a split second and then it begins moving downward, then increasing at 9.81m/s^2 until it reaches maximum velocity.

Can a body moving with certain velocity in the direction of east have acceleration in the direction of west?

Yes, a body moving with a constant velocity in the east direction can still have acceleration in the west direction if an external force is applied in that direction. Acceleration is the rate of change of velocity, so even if the velocity is constant, a change in direction or magnitude of the velocity can still result in acceleration.


Is An object moving with a certain direction with an acceleration in the perpendicular direction?

Yes, the object will move in a curved path due to the combined effect of the velocity in one direction and acceleration in the perpendicular direction. This is known as projectile motion. The acceleration perpendicular to the initial velocity will change the direction of motion but not the speed.


What is the direction of acceleration in a moving car?

The direction of acceleration in a moving car is in the direction of the change in velocity, either speeding up or slowing down.


What is the different between velocity and acceleration?

Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.


Can a body moving with certain velocity in the direction of east have aeleration in the direction of west explain how?

Yes a body moving with some velocity in the direction of east have acceleration in the west because when the body will stop or exerts brakes so the body will move a little back and acceleration will be produced in the opposite direction which is west.


How are velocity and acceleration different?

Velocity is the rate of change of position of an object with respect to time, while acceleration is the rate of change of velocity of an object with respect to time. Velocity describes how fast an object is moving and in which direction, while acceleration describes how quickly the velocity of an object is changing, either in speed or direction.


What moving object speed up in what direct is the acceleration?

The acceleration is the same direction of the velocity


What is the direction of average acceleration?

Average acceleration points in the same direction as the change in velocity over time. If the velocity is increasing, the average acceleration will be in the same direction as the velocity. If the velocity is decreasing, the average acceleration will be in the opposite direction.


What is Three ways in which a cars velocity will change?

Acceleration: When a car speeds up or slows down, its velocity changes due to an acceleration in the direction of motion. Deceleration: If the car is moving in a certain direction and slows down, its velocity decreases. Change in direction: If the car turns a corner or changes its course, its velocity changes as it moves in a different direction.


Can something have an acceleration while moving at a constant velocity?

No. A object can have acceleration while moving at a constant speed (like the earth in its orbit around the sun). But once you use the word "velocity", you've expanded the decription of its motion to include the direction as well as the speed. The definition of acceleration is a change in either speed or direction, so if there is acceleration, then either the speed or the direction of the velocity (or both) is changing, so the velocity is not constant.


Is it possible for a body to have an acceleration when moving with constant velocity?

No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.


How an object could still be moving with the 0 acceleration?

An object can still be moving with zero acceleration if it is moving at a constant velocity. When acceleration is zero, the object's velocity remains constant, meaning it continues to move at the same speed and in the same direction without any change in speed or direction.
