Change in velocity
because velocity is a vector, change in velocity is also a vector, change in velocity has magnitude and direction
Linear Acceleration
Rate of change of linear velocity, gives average acceleration from t0-t1
Acceleration as change in speed
acceleration can reflect a change in the magnitude of velocity without a change in direction
Acceleration as change in direction
acceleration can reflect a change in the direction of velocity without a change in magnitude
Acceleration in 1D
velocity and acceleration…
-in same direction: velocity increases magnitude
-in opposite direction: velocity decreases magnitude
Effects of instantaneous acceleration
-with direction of motion, speed increases
-against direction of motion, speed decreases
Propulsive Phase
-magnitude of velocity increases
-velocity and acceleration in same direction
Braking Phase
-magnitude of velocity decreases
-velocity and acceleration in opposite direction
Static Phase
-velocity stays constant
-acceleration=0
