AS1 1.5 Dynamics

Question 1

Describe “projectile motion”

Answer 1

• A constant velocity in the horizontal direction
• Uniform Deceleration in the vertical direction

Question 2

What are the two constants in projectile motion?

Answer 2

1. The horizontal velocity remains the same
2. The acceleration due to gravity is -9.81m/s^2

Question 3

What is important to consider in projectile motion?

Answer 3

1. Horizontal and vertical motion must be considered independently
2. The only thing linking horizontal and vertical motion is time
3. There is no acceleration in the horizontal plane

Question 4

What are the quantities you take note of in the horizontal and vertical motion?

Answer 4

Horizontal : speed, distance, time
Vertical : displacement, initial velocity, final velocity, acceleration, time

Question 5

What is the name given to the shape of the curved path in projectile motion?

Answer 5

Parabola
