### Position, Velocity, and Acceleration

Review- 3-C

Position:

Velocity:

Acceleration:

Acceleration vs Velocity
• If the signs are the same, then the particle’s speed is increasing
• If the signs are opposite, then the particle’s speed is decreasing
• If the velocity is zero and acceleration is not zero, then the particle is momentarily stopped and changing directions.
Velocity
• If v(t) > 0 then the particle is moving to the right
• If v(t) < 0 then the particle is moving to the left
• If v(t) = 0 then the particle has momentarily stopped or is changing directions
The position of a particle moving along the x - axis at time t is given by

for 0≤ t ≤ 20

a) Determine when the particle is moving to the left?

The position of a particle moving along the x - axis at time t is given by

for 0≤ t ≤ 20

b) Determine when the particle changes direction and find its position.

The position of a particle moving along the x - axis at time t is given by

for 0≤ t ≤ 20

c) Determine when the particle is speeding up?

The position of a particle moving along the x - axis at time t is given by

for 0≤ t ≤ 20

d) find the total distance travelled

An object is moving along the x-axis according to

for t ≥ 0 find all intervals during which the object is moving in a positive direction.

An object is moving along the x-axis

according to

for 0≤ t ≤ 6 find the intervals during which the object is speeding up.

4) If find the total distance traveled by the particle on the interval (0,4).
