Question

3. In order to have velocity what is needed? 4. What is an example of acceleration?

Answer 1

Answer: Velocity needs both magnitude and direction

Step-by-step explanation:

Velocity is defined as a Vector quantity which implies that one needs to know both the magnitude and the direction of the object, as a reference frame. The expression for velocity is defined as:

Velocity = Distance * Time <=> V= dt

Acceleration occurs when an object initially moving with a constant velocity, changes motion and velocity increases with time. The expression for acceleration is defined as:

Acceleration = Velocity * Time <=> A= Vt

A typical example of acceleration is a Free Falling Object (i.e. letting a ball drop from a building)
