PHYSICS 15 Projectile Motion

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position is the projectile moving with the fastest upward velocity?

• Position A

• Position B

• Position C

• At Positions A, B, and C. The upward velocity is equally fast.

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position is the projectile moving with the fastest downward velocity?

• Position E

• Position F

• Position G

• At Positions E, F, and G. The downward velocity is equally fast.

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position or positions is the projectile accelerated in the down direction?

• Position A

• Position D

• Position G

• At all positions (A, B, C, D, E, F, & G.)

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position or positions is the projectile slowing in the up direction?

• Position A

• Position B & C

• Position C

• Positions A, B, & C

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position or positions is the projectile slowing in the down direction?

• Position G

• Position E & F

• Positions E, F, & G.

• At no positions.

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

At which position or positions is the projectile moving with the fastest horizontal velocity through its range?

• Position A

• Position D

• Positions G

• At all positions (A, B, C, D, E, F, & G).

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

Which statement accurately describes what happens at Position D?

• The projectile stops for an instant, changes direction.

• The projectile stops for an instant, immediately falls to the ground.

• The projectile continues to move, but changes direction.

• The projectile continues to move, but immediately falls to the ground.

The diagram shows parabolic projectile motion. The object is launched at A. The object impacts the ground at G.

Which statement accurately describes what happens at Position D?

• The projectile moves with only horizontal motion.

• The projectile is instantaneously motionless (not moving).

• The projectile moves with both up and down motion at the same time.

• The projectile has zero acceleration.

The diagram shows horizontal projectile motion. The object is launched at A. The object impacts the ground at E.

Which statement accurately describes what happens at Position A?
