Projectile motion

Question 1

Define projectile motion

Answer 1

The movement of an object or body through air

Question 2

Define horizontal displacement

Answer 2

The shortest distance from the start to finish point in a line parallel to the ground

Question 3

What 3 factors affect horizontal displacement?

Answer 3

Angle of release
Speed of release
Height of release

Question 4

When the release high and landing height are equal, what is the optimal angle of release?

Answer 4

45 degrees

Question 5

When release height is lower than the landing height, what is the optimal angle of release?

Answer 5

greater than 45 degrees

Question 6

When release height is greater than landing height, what is the optimal angle of release?

Answer 6

less than 45 degrees

Question 7

How does an increase in speed of release affect horizontal displacement?

Answer 7

Increase in velocity increases horizontal displacement

Question 8

How does a greater height of release affect the horizontal displacement?

Answer 8

A greater release height causes a greater horizontal displacement

Question 9

What are the characteristics of a projectile that follows a true parabola + example

Answer 9

Large weight force
Small air resistance force

Shot put

Question 10

What 2 forces affect projectile motion?

Answer 10

Weight
Air resistance
