Acceleration describes the motion of a car. Acceleration is defined as an increase in the rate or speed of something.
Speed descibes the rate of motion of an object. Velocity describes rate of motion (speed) of an objectin a specific direction. For example - the car's speed was 60mph, the car's velocity was west at 60mph.
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
Velocity only describes the speed. Vector describes both speed and direction. That entails trigonometry.
Miles per hour (MPH), or kilometres per hour (KPH) are time travelled by the car over a measured distance.
Velocity describes the speed and direction of an object.velocityvelocity
Velocity, or Speed
The speed of the car.
Velocity describes both the speed and direction an object is moving.
10m/s describes speed.
by itself it is speed; if associated with a direction it is velocity
if its km/h then it describes your speed in kilometers per hour
