3: Projectile Motion

Projectile motion

is defined as a form of motion in which an object or particle is thrown near the earth’s surface, and it moves along a curved path under the action of gravity only

45 degrees

To attain the maximum possible horizontal range, a projectile must be fired through an angle ___ with horizontal.

Rotational Motion

is the motion by which a body moves in circles and that the centers of these circles all on one line called the axis of rotation

Angular velocity

defined as the rate of change of angular position

Angular acceleration

defined as the rate of change of angular velocity

Newton’s second law of motion

If the resultant force acting on a particle is not zero, the particle will have an acceleration proportional to the magnitude of the resultant and in the direction of this resultant force.
