Kinematics  Mechanics - is the field in Physics dealing with the effects of forces on an object. Kinematics- studies the Dynamics- concerned on how description of motion of motions are affected by forces objects. that act on objects.  Direction: Inspect the cars below, and then choose appropriate motion of the cars.

Velocity- vector; displacement over time, how fast or slow an object moves with consideration of the initial and final position and the direction the object travels Average Speed- the total distance traveled by the object in a particular time interval. Acceleration vs Deceleration  Acceleration vs Deceleration Acceleration- the rate of Deceleration- a negative change in velocity acceleration means that speed a=change in velocity/ time decreases through time interval direction of the acceleration following the direction of the vector with the higher magnitude. Equations for Projectile Motion
