Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. ... The rate at which velocity changes over time;an object accelerates its speed,direction, or both change.

Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Acceleration is defined as the rate of change of an object's velocity. Just like the derivative of the position function gives you the velocity as a function of time, the derivative of the velocity function (which is also the second derivative of the position function) gives you the acceleration as a function of time.

Speed is a scalar quantity while acceleration is a vector quantity. Speed is related to the rate of motion while acceleration is related to the rate of motion as well as the direction of motion.

Acceleration. When an object changes velocity, it accelerates. Acceleration is the change in velocity per second and is measured in m/s 2. The relationship between acceleration, velocity change and the time taken for the change is given by this formula. acceleration = change in velocity time taken = v - u t.

Velocity is the rate of displacement of an object. ... Acceleration is the rate of change of velocity of an object. It is measured in m/s2. They are both vector quantities i.e. both magnitude and direction are required to fully specify them.

Velocity includes both speed and direction of motion. Acceleration is a change in velocity. Velocity changes when either the speed, the direction, or both the speed and the direction change.

Acceleration is a vector in the same direction as the change in velocity, Δv. Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed or direction, or both.

Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. ... Both are equal to mass times change in velocity divided by time. And therefore both are equal to Force.

Acceleration is the rate of change of velocity. It is the amount that velocity changes per unit time. This is when: acceleration (α) is measured in metres per second squared (m/s²)

Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

Acceleration is a vector in the same direction as the change in velocity, Δv. Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed or direction, or both. ... When an object slows down, its acceleration is opposite to the direction of its motion.

The acceleration of an object is its change in velocity over an increment of time. This can mean a change in the object's speed or direction. Average acceleration is the change of velocity over a period of time. ... Constant or uniform acceleration is when the velocity changes the same amount in every equal time period.

Acceleration of a body moving with uniform velocity is ZERO. Acceleration is rate of change of speed with respect to time.

Velocity is the displacement by an object per unit time. Acceleration is the change in velocity per unit time. So, a body in constant speed is said to have zero acceleration.

Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.
