Projectile Motions

Question 1

What is horizontal displacement?

Answer 1

The shortest distance from the starting point to the finishing point in a line parallel to the ground

Question 2

What are the 3 factors that effect horizontal displacement?

Answer 2

Angle of release
Speed of release
Height of release

Question 3

How does speed of release help?

Answer 3

Greater release velocity of projectile = greater horizontal displacement traveled

Question 4

How does height of release effect horizontal displacement?

Answer 4

Greater release height = greater horizontal displacement

Question 5

How does angle of release effect horizontal displacement?

Answer 5

optimum angle of release- angle between the horizontal and the direction of projectile at release.

When release height and landing height is equal it will be 45 degrees

If release height is lower than landing height it will be higher than 45 degrees

If release height is higher than landing height it will be lower than 45 degrees

Question 6

What is a parabolic curve?

Answer 6

curve with matching left and right sides

Shot put = parabolic

shuttlecock = non parabolic
