Projectile motion

Question 1

projectile motion

Answer 1

refers to the motion of an object or person that is projected through the air

Question 2

horizontal displacement

Answer 2

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

Question 3

3 factors affecting horizontal displacement

Answer 3

1) Height of release
- greater the release height the greater horizontal displacement.
- this is due to the force of gravity constantly acting on the mass of a projectile.

Question 4

Factors affecting horizontal displacement - 2) speed of release

Answer 4

greater the velocity the greater the horizontal displacement.

Question 5

Factors affecting horizontal displacement - 3) Angle of release

Answer 5

• optimum angle is dependent on release height and landing height.
• both equal then optimum angle in 45 degrees

Question 6

parabola

Answer 6

a curve that is symmetrical at its highest point

Question 7

Factors affecting projectile flight paths - weight and air resistance

Answer 7

• both these forces affect projectiles in the air
• they influenced whether a projectile has a TRUE or DISTORTED parabola.

Question 8

True parabola

Answer 8

projectiles with a larger weight force have a small air resistance and follow a true parabolic flight path
EG: shotput

Question 9

Distorted parabola

Answer 9

projectiles with a lighter weight force and specific design have a greater air resistance and result in a distorted parabolic flight path
