Ignoring air resistance, Acceleration of a projectile is:
- A
Zero
- B
10 m/s^2 vertically upward
- C
10 m/s^2 vertically downward
- D
10 m/s^2
Ignoring air resistance, the acceleration of a projectile is constant and is equal to the acceleration due to gravity (approximately 9.8 m/s² downwards).
Here's why:
- Only force acting: When air resistance is ignored, the only force acting on a projectile after it's launched is gravity.
- Constant gravitational force: The force of gravity is constant near the Earth's surface, resulting in a constant downward acceleration.
- No horizontal acceleration: Since there are no horizontal forces acting on the projectile (again, ignoring air resistance), there is no horizontal acceleration. The horizontal velocity remains constant.
Therefore, the acceleration of a projectile (ignoring air resistance) is entirely vertical and constant, directed downwards
