AS1 1.5 Dynamics

Question 1

Describe “projectile motion”

Answer 1

Projectile motion is the motion of an object that is thrown at an angle with gravity acting upon it, so it moves in an arch like motion if the object is thrown upwards

Question 2

Describe “projectile motion”

Answer 2

Projectile motion is the motion of an object that is thrown at an angle with gravity acting upon it, so it moves in an arch like motion if the object is thrown upwards

Question 3

What are the two constants in projectile motion?

Answer 3

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

Question 4

What is important to consider in projectile motion?

Answer 4

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 5

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

Answer 5

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