### 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.

### Can two direction of velocity of an object change when acceleration is constant?

An object can have only one velocity at any point in time. That velocity can have components in two (or more) directions.If acceleration is constant (but non-zero), then the velocity in any direction other than perpendicular to the direction of the acceleration must change.

### Is it possible that the velocity of a body changes and its acceleration remains constant?

Yes, it is possible. When a body moves in a circular path at a constant speed, its velocity changes direction continuously, but its magnitude remains constant. In this case, the acceleration is constant in direction and magnitude, since it is always directed towards the center of the circular path.

### Can two directions of velocity of an object change when acceleration is constant?

An object can have only one velocity at any point in time. That velocity can have components in two (or more) directions.If acceleration is constant (but non-zero), then the velocity in any direction other than perpendicular to the direction of the acceleration must change.

### When a cart is changing direction is it acceleration?

Yes, changing direction involves acceleration because acceleration is the rate of change of velocity. When an object changes direction, its velocity changes, which means it is experiencing acceleration.

### If there is a constant velocity of 30 ms. What is its acceleration?

Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.

### What is the process of changing velosity?

To change velocity, an object must undergo acceleration. Acceleration is the rate of change of velocity with respect to time. This can be achieved by applying a force on the object in the direction of desired velocity change.

### What MUST be true about an object's acceleration as it is traveling in the positive direction and slowing down?

The object's acceleration must be in the negative direction, opposing its velocity in the positive direction. This negative acceleration is also known as deceleration and causes the object to slow down.

### Can a body has velocityin the east and the acceleration in the west?

No, a body cannot have velocity in one direction and acceleration in the opposite direction simultaneously. Velocity and acceleration must be in the same direction for consistent motion.

### When velocity is increasing can acceleration remains constant?

No, if velocity is increasing then acceleration cannot remain constant. Acceleration is the rate of change of velocity, so if velocity is increasing, then acceleration must also be changing to cause that increase in velocity.

### Can an object acceleration if its velocity is constant?

No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.

### A moving body must undergo a change in?

A moving body must undergo a change in its velocity to show acceleration. Velocity is a vector quantity that includes both speed and direction so any change in speed, direction, or both constitutes a change in velocity, resulting in acceleration.
