Answer 4

projectile motion

Question 5

Answer 5

projectile motion

Question 6

2 types of circular motions

Answer 6

1.uniform circular motion
2.non-uniform circular motion

Question 7

is a type of motion that has a constant speed where the movements is consistent

Answer 7

uniform circular motion

Question 8

is a type of circular motion that slows down and speeds up at any point in the path.

Answer 8

non-uniform circular motion

Question 9
