Acceleration

Question 1

What is acceleration?

Answer 1

The change in velocity during a given time interval

Question 2

Acceleration formula?

Answer 2

a->=vf-> -vi->/t

Question 3

Units and what they mean in acceleration formula?

Answer 3

a->=acceleration (m/s2)
vf->= final velocity (m/s)
vi->= initial velocity (m/s)
T= time interval (s)

Question 4

In acceleration can also use delta which is?

Answer 4

Can use delta △ to represent change in.

So acceleration formula could be:

a->= △v->/t

Question 5

When we slow down what do we call it?

Answer 5

Deacceleration also referred to as negative acceleration

Question 6

When does an object accelerate?

Answer 6

Whenever its velocity changes, which happens when its speed or direction, or both, are changing

Question 7

The acceleration of an object is due to the net force on the object and the object’s?

Answer 7

Mass
