Question 3

3 ways acceleration changes:

Answer 3

1) increasing speed
2) decreasing speed
3) changing directions

Question 4

Gravity is:

Answer 4

a force that pulls objects towards each other

Question 5

What are 2 factors that affect gravitational attraction between objects?

Answer 5

1) the mass of the object

2) the distance between objects

Question 6

What is Newton’s 1st Law of Motion?

Answer 6

an object in motion will stay in motion, an object at rest will stay at rest unless acted upon by an outside force

Question 7

What is Newton’s 2nd Law of Motion?

Answer 7

acceleration depends upon the object’s mass and force acting on the object

Question 8
