Variable Acceleration And Forces 1

Question 1

How do you move from s to v to a? And visa versa

Answer 1

To move from s to v to a, you differentiate

And

To move from a to v to s, you integrate

Question 2

What is Newton’s First Law of Motion?

Answer 2

An object at rest will stay at rest or if moving with constant velocity will stay at constant velocity, unless acted upon by a resultant external force.

Question 3

What does a resultant force cause?

Answer 3

A resultant force acting on an object will cause it to accelerate in the same direction as the resultant force.

Question 4

How do you find the resultant force of two or more forces that are given as vectors?

Answer 4

You add the vectors.

Question 5

What is the variable acceleration formulae for velocity?

Answer 5

v = ds/ dt

Question 6

What is the variable acceleration formulae for acceleration?

Answer 6

a = dv/ dt

Or

a = d²s / dt²

Question 7

What is the variable acceleration formulae for displacement?

Answer 7

s = ∫v dt + c

Question 8

What is the variable acceleration formulae for velocity?

Answer 8

v = ∫a dt + c
