Velocity and Acceleration

Question 1

How do you calculate how fast something moves?

Answer 1

By timing it (which speed is used for)

Question 2

What’s the measurement that’s used for speed in science called?

Answer 2

Velocity: includes the directions that an object is traveling

Question 3

What is acceleration?

Answer 3

Acceleration is when an object changes it’s velocity
(includes the change of speed, or the change of directions)

Question 4

How do Newton’s 1st and 2nd law work together?

Answer 4

• Objects like to do what they do, it takes force to change that (1st law)

Therefore

• The bigger an object is/the greater acceleration that’s needed, means there’s more force needed (2nd law)
