The rate of change of velocity is known as acceleration. This can come in different forms (linear / nonlinear acceleration, angular acceleration ect).

When cars are changing direction they are also changing what?
They are changing velocity. Velocity is the measure of speed and direction
What is measure of velocity?
It is a measure of speed in a specific direction
What does constant velocity or acceleration mean?
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
What is needed to measure velocity of an object?
In order to measure velocity you need displacement (a start location and an end location) and time.
What is the definition of speed and the definition of velocity?
Speed is how fast something is going when the direction in which it is travelling is unimportant. Velocity is a measurement of the rate at which an object is changing its position. As such, in order to measure it, one must define both the speed at which an object is moving, and also the direction of movement.

Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.

How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).
What is Velocity a measure of?
It is a measure of speed in a specific direction
Momentum is the measure of?
velocity
What does a velometer measure?
Air velocity in ventilation systems
What is needed to measure velocity of an object?

What is Revolutions per minute in CNC?
are a measure of angular velocity whereas metres per minute are a measure of linear velocity.

Can a body have constant velocity and changing speed?
No, in order for the velocity to be constant, the speed has to be constant. Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour). Velocity is a vector, which indicates that it needs a measure of its displacement and a direction. (A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout). However, a body can not have a constant velocity with a changing speed. A car can not be slowing down yet still be going the same speed and direction.
