1
New cards

Change in velocity

because velocity is a vector, change in velocity is also a vector, change in velocity has magnitude and direction

2
New cards

Linear Acceleration

Rate of change of linear velocity, gives average acceleration from t0-t1

3
New cards

Acceleration as change in speed

acceleration can reflect a change in the magnitude of velocity without a change in direction

4
New cards

Acceleration as change in direction

acceleration can reflect a change in the direction of velocity without a change in magnitude

5
New cards

Acceleration in 1D

velocity and acceleration…

-in same direction: velocity increases magnitude

-in opposite direction: velocity decreases magnitude

6
New cards

Effects of instantaneous acceleration

-with direction of motion, speed increases

-against direction of motion, speed decreases

7
New cards

Propulsive Phase

-magnitude of velocity increases

-velocity and acceleration in same direction

8
New cards

Braking Phase

-magnitude of velocity decreases

-velocity and acceleration in opposite direction

9
New cards

Static Phase

-velocity stays constant

-acceleration=0
