In what two ways can velocity be changed?
Velocity changes when the direction of the motion changes.
Why is a particle in uniform circular motion not moving at a constant velocity?
No. Velocity has direction and magnitude. The magnitude can be constant, but if the body is in circular motion, the direction of the movement is constantly changing, which means that the velocity is constantly changing. Changing velocity means that the body is accelerating. In this case, because the motion of the body is always changing away from a straight line to cause it to go round the circle, the acceleration acts towards the centre of the circle.
Changing direction is an example of a kind of?
Acceleration
What is the definition of non uniform motion in physics?
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
What does changing velocity means?
Changing velocity refers to a change in an object's speed and/or direction of motion. An increase in velocity means the object is speeding up, while a decrease means it is slowing down. The direction of the velocity vector also plays a crucial role in determining the overall motion of the object.

When does a particle in motion have non-uniform velocity?
That simply means that its velocity is changing.

What type of motion is occurring when the slope of a velocity vs. time graph is zero?
It means that the velocity is constant, or not changing.

How can velocity be changed?
Velocity can be changed by applying a force in the direction of motion. An increase in force will result in an increase in velocity, while a decrease in force will cause velocity to decrease. Another way to change velocity is by changing the direction of motion, which can be achieved by applying a force perpendicular to the current motion.
Is the velocity constant for an object in uniform circular and why?
No, the velocity is not constant for an object in uniform circular motion because the direction of the velocity is changing continuously due to the object's changing direction as it moves along the circular path. The magnitude of the velocity (speed) remains constant, but the velocity vector is constantly changing direction.
What is the difference between acceleration and velocity?
Velocity is the rate at which an object changes its position, while acceleration is the rate at which the velocity of an object changes. In other words, velocity is the speed and direction of motion, whereas acceleration is the change in speed or direction of motion.
What is acceleration of body having uniform motion?
A body experiencing uniform motion does not have any acceleration. Acceleration is the rate of change of velocity, and since the velocity of a body in uniform motion remains constant, there is no change in velocity and therefore no acceleration.
Which characteristic of motion could change without changing the velocity?
Well, we know that velocity describes the speed and direction of motion, so you can't change either of those. We don't usually think of 'position' as a characteristic of motion, but if we try hard to please you, then we might observe that the position changes while velocity remains constant.
