Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
Uniform velocity is constant speed in a straight line, while variable velocity changes in speed or direction over time. Uniform velocity has no acceleration, whereas variable velocity may have acceleration due to changes in speed or direction.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
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.
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
Velocity . . . what speed and direction something is moving. Acceleration . . . how fast the speed and/or direction of its motion are changing.
Constant velocity refers to an object moving at a steady speed in a straight line, while constant acceleration means the object is changing its speed at a consistent rate.
Velocity is the change in displacement in a unit time in a specific direction. Speed is the magnitude of velocity and has no direction. Acceleration is the change in velocity in a unit time.
Velocity is the rate of change of an object's position with respect to time, including its speed and direction. Acceleration, on the other hand, is the rate of change of an object's velocity with respect to time, indicating how quickly the object's velocity is changing. Acceleration may result from changes in speed, direction, or both.
The relationship between velocity and acceleration affects how an object moves. When acceleration is positive, velocity increases, causing the object to speed up. When acceleration is negative, velocity decreases, causing the object to slow down. If acceleration is zero, velocity remains constant, and the object moves at a steady speed.
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
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.
If an object's speed is changing ... either growing or shrinking ... or the direction of its motion is changing, or any combination of these changes, then the object is said to be accelerated.
