is mph velocity or acceleration?

We also learned that speed is a scalar quantity, which is one that requires only a magnitude, while velocity is a vector quantity, which is one that requires a magnitude (also mph) and a direction. The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).

Speed is the rate at which an object covers distance in a particular time. ... Velocity is the displacement traveled by a body per unit time. It is a vector quantity.

Motion is a combination of acceleration and velocity(speed). Speed is distance travelled/ time taken. ... Acceleration is the change in velocity in the time frame of the velocity. eg if the velocity is in units of meters per second then the acceleration is in meters per second per second.

Acceleration is defined as the rate of change of velocity. constant velocity is the velocity which doesn't change per time. So,if the velocity is constant,the acceleration is zero.

Velocity is the rate of change of position. Acceleration is the rate of change of velocity! They are both rates and the both involve movement. They both are vectors, involving both an amount and a direction.

Speed is the rate at which something moves, distance over time. Velocity is speed with a direction, so distance over time with a specific direction. And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes.

Velocity is a vector quantity which has a direction. The direction of the velocity vector is always in the direction which the object is moving. Direction of Acceleration: Acceleration is a vector quantity and it has a direction.

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity.

Acceleration is a vector quantity. Acceleration is the rate of change of velocity. (when velocity changes -> acceleration exists) If an object is changing its velocity, i.e. changing its speed or changing its direction, then it is said to be accelerating. Acceleration = Velocity / Time (Acceleration)

Acceleration. Acceleration is how fast velocity changes: Speeding up. Slowing down (also called deceleration) Changing direction.

Acceleration. ... 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. v = final velocity and u = starting velocity.

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).

The short answer is that velocity is the speed with a direction, while speeddoes not have a direction. ... Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc....

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. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

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)

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.
