A projectile is a moving object that has only one force acting upon it: the force of gravity.
Projectile motion usually refers to the trajectory (path) followed by a projectile. Projectile motion may also refer to the kinematic characteristics of a projectile, such as its displacement, velocity, or acceleration.
The path or predicted path of a projectile.
1. In the absence of air resistance, a ball of mass m is thrown straight up and reaches a height of 10 m. The net force on the ball half-way up (at 5 m up) is
2: A ball is kicked 10 m/s horizontally off a cliff. After 1 second, its speed is approximately
a. 10 m/s
b. 14 m/s
c. 20 m/s
d. 28 m/s
