Acceleration is the change in velocity. That is, if you're going faster, you're accelerating in the positive direction. If you're going slower, you're accelerating in the negative direction, or decelerating.
Velocity is the change in position. Measured in meters/second most of the time, it describes how quickly you are moving and in what direction.
Speed is the absolute value of velocity. Unlike velocity and acceleration, speed is a scalar, not a vector (which means it has an amount, but no direction). If you're moving backwards at 2 m/s, your velocity is -2 m/s, but your speed is still just 2 m/s.
Acceleration is the rate at which an object changes its velocity, either in magnitude or direction, over time. It is a vector quantity, meaning it has both magnitude and direction. Velocity, on the other hand, is the rate of change of an object's position with respect to time and is also a vector quantity, representing both speed and direction.

What are some differences and similarities between acceleration and velocity?
Acceleration is the rate of change of velocity over time, while velocity is the rate of change of position over time. Both acceleration and velocity are vector quantities, meaning they have both magnitude and direction. Acceleration can either be in the same direction as velocity (causing an increase in speed) or in the opposite direction (causing a decrease in speed).
What is the difference between uniform and variable velocity?
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.
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 speed and velocity?
Acceleration is the rate of change of velocity over time. It measures how quickly an object's velocity is changing. Speed is the rate at which an object covers distance, whereas velocity includes both speed and direction.
When you press your bicycle's brakeswhat happens to your speedvelocityand acceleration?
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.

What is the difference between speed velocity acceleration?
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
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.
What is the differnece between speed acceleration and velocity?
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.
What is the differences between speed and velocity is that velocity includes?
Velocity includes a Direction.
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.
What is the difference between uniform and variable velocity?
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.
What is one similarity to speed velocity acceleration?
Speed, velocity, and acceleration all have momentum.
Are speed and acceleration the same?
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
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.
What are the importance of speed velocity and acceleration in sports?
what are important speed, velocity and acceleration in several sports
What does acceleration have to do with velocity?
Velocity is speed in a given direction Acceleration is the rate in which you change velocity.
