What is Projectile Motion?

Projectile motion describes the motion of an object thrown or projected into the air, subject only to the acceleration of gravity.

New cards

What are the key assumptions made when analyzing projectile motion?

  1. Air resistance is negligible.
  2. The acceleration due to gravity (g) is constant and directed downwards.
  3. The Earth's rotation is negligible.

Describe the horizontal motion of a projectile.

The horizontal motion of a projectile is characterized by a constant velocity (assuming no air resistance), meaning there is zero horizontal acceleration.

4
New cards

Describe the vertical motion of a projectile.

The vertical motion of a projectile is characterized by a constant downward acceleration due to gravity (g), similar to free fall.
