Projectile Motion

Question 1

Two forces experienced by an object thrown into the Earth’s gravity field

Answer 1

1) Initial accelerating force

2) Force of the gravity field

Question 2

Object’s projectile trajectory

Answer 2

Is parabolic

Depends on:

• Its initial velocity
• The strength of the gravity field

Question 3

Characteristics of Projectile Motion

Answer 3

• Horizontal component (velocity) remains unchanged

- Vertical component (velocity) is changed throughout by the acceleration due to gravity
