ocr a level physics projectile motion Quiz Practice…

Weight (due to gravity) — Gravity is the only force acting in the vertical direction, causing acceleration downwards.

0 m/s² — There are no horizontal forces, so there is no horizontal acceleration. The horizontal velocity remains constant.

9.81 m/s² (downwards) — The only vertical force is weight, causing constant acceleration due to gravity (9.81 m/s² downwards).

Zero — A horizontally launched projectile has no initial vertical component of velocity.

A parabola — The constant horizontal velocity and constant vertical acceleration combine to create a parabolic trajectory.

Question 1 of 5

Which of the following forces acts on a projectile during its flight, neglecting air resistance?

Gravity is the only force acting in the vertical direction, causing acceleration downwards.

Question 2 of 5

There are no horizontal forces, so there is no horizontal acceleration. The horizontal velocity remains constant.

Question 3 of 5

The only vertical force is weight, causing constant acceleration due to gravity (9.81 m/s² downwards).

Question 4 of 5

A horizontally launched projectile has no initial vertical component of velocity.

Question 5 of 5

The constant horizontal velocity and constant vertical acceleration combine to create a parabolic trajectory.
