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.
