what is the difference between acceleration and average acceleration?
105156
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 is in the direction of motion, when you are increasing the speed of the car moving along a straight line. b. Acceleration is against the direction of motion, when brakes are applied to the car in motion.

Acceleration is defined as a change in velocity. Velocity is defined as a change in distance per unit of time. Acceleration occurs because a force is applied to an object. As long as the force is applied the object will accelerate.

Acceleration is simply a rate of change of velocity. So the magnitude tells you, how quickly velocity changes.

The dimensional equation of the average acceleration is [aa] = [LT. The unit of measurement in the International System (S.I.) of the acceleration is meter per second squared (m/s2). A body with a 1 m/s2 acceleration changes its velocity by 1 meter/second every second.

Acceleration, (symbol: a) is defined as the rate of change of velocity. It is thus a vector quantity with dimension length/time². In SI units, acceleration is measured in meters/second².

The difference with the acceleration vector is that the vector form also encapsulates the direction in which this gain in speed is happening. So as an example an acceleration magnitude of 2 m/s2 means that every second your speed is 2 m/s higher.

acceleration. the rate at which velocity changes is called. acceleration. in an acceleration graph showing speed versus time, a straight line shows the acceleration is. constant.

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

Summary: Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity while acceleration is a vector quantity.

Acceleration is the rate of change of an object's velocity. Acceleration is a vector quantity, requiring both a magnitude and a direction. ... Velocity changes if the direction of travel or speed changes. Even if the object is moving at a constant speed, the object can be accelerating if the direction of travel changes.

Explanation: Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.

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.

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

Acceleration is the change in velocity per time. Acceleration, then, is the change in my velocity per unit time. ... Thus, our acceleration is 4 m/s/s in the +x direction. So, acceleration is the change in velocity per time. Speed is the magnitude of velocity.
