A rabbit is hopping uphill with a positive velocity while having a negative acceleration due to gravity. Describe the motion of the bunny in terms of speed. (speeding up or slowing down)

The bunny is slowing down. When the direction of velocity and acceleration are opposite, it slows down!!!

400

Draw a position vs. time graph that shows constant, positive acceleration.

Ms. Donahue judges. (Upward curve)

500

Draw a Position vs. Time graph that shows motion towards the reference point.

Mrs. Martin decides (Should be a line that goes towards the origin)

Galileo

What is the equation symbol and SI unit for acceleration?

Equation Symbol: a SI unit: m/s^2

200

True/False: Velocity is different from speed in that velocity is speed in a given direction.

True

What does the slope of a position vs. time graph tell us? What is the SI Units for the slope of the position vs. time graph?

The slope shows velocity. The SI unit is m/s.

500

In the following problem, write out the proper equation and solve the problem using the proper SI units:A stone is dropped from a cliff with no initial velocity. The stone has a vertical acceleration of 9.8 m/s2. After it has fallen 128.6 m, what is the stone’s final velocity?

Equation:a = (vf^2 – vi^2)/2Δd Substitute:9.8 = (vf^2 – 0^2)/ 2(128.6) Cross Mult : 2520.56 = vf^2 Take the square root : vf = 50.2 m/s Solve: vf= 50.2 m/s

Name all of the Givens and Unknowns in the following problem:If the average speed of a cheetah is 21.7 m/s, how far can it run in 3.0 seconds?

v= 21.7 m/s t= 3.0 s d= ?? m

400

What does the slope of a velocity vs. time graph tell us? What is the SI unit for the slope of a velocity vs. time graph?

The slope of a velocity vs. time graph shows us Acceleration. The SI unit is m/s^2

500

In the following problem, write out the proper equation and solve using the correct S.I. Units:Starting from rest, a car undergoes a constant acceleration of 6.0 m/s2. How far will the car travel in the first second of travel?

Equation:∆ d = (vi)t + (1/2) a (t)^2 Substitute:∆ d = (0)(1) + (1/2)(6)(1)^2 Solve:Δd = 3.0 m

100

What is the equation symbol and SI unit for displacement/ distance?

Equation Symbol: d SI Unit: m

200

True/ False: Even though a car is slowing down, it is still experiencing an acceleration.

TRUE. Negative acceleration could mean slowing down.

300

Name ALL of the Givens and Unknowns in the following problem:Starting from rest, a car undergoes a constant acceleration of 6.0 m/s2. How far will the car travel in the first second of travel?

a= 6.0 m/s^2 vi= 0 m/s t= 1 s d= ?? m

400

Draw a position vs. time graph that shows motion with constant non-zero acceleration.

Ms. Donahue decides (it should be a position/time graph that is curved)

500

In the following problem, write out the proper equation and solve the problem using correct SI units:How far does a car travel with an acceleration of 4.0 m/s2 take to go from 10 m/s to 30 m/s?

Equation: a = (vf2 – vi2)/ 2Δd Substitute: 4 = (30^2 – 10^2)/2Δd Switch the 4 and Δd Δd = (302 – 102)/ 2(4) Δd = 800/ 8 Solve: Δd = 100 m
