Study guide for Chapter 3 physics test

L/O vocabulary – be able to define the following vocabulary using pictures and/or words. Be able to

match units to words and know which are vectors and which are scalars. Questions will be matching,

multiple choice, fill in the blank or short answer.

Acceleration due to gravity Average Acceleration Displacement Distance Free fall Speed Terminal velocity Velocity

L/O interpret velocity time graphs – be able to determine the velocity, acceleration and displacement of an object using its velocity graphed over time. Calculate the acceleration from: 0 – 3 seconds ; 3 – 7 seconds; 7 – 10 seconds; 10-11 seconds; 11-14 seconds What is the velocity at: 0 s; 1 s, 3s, 5s, 8s, 10s, 12 s What is the displacement from: 0 – 3 seconds ; 3 – 5 seconds; 5 – 7 seconds; 7-10 seconds; 10- 11seconds; 11-14 seconds Answers ( a = 6.67;-10; 0; 20; 0) (v = 0,5,20,0,-20,-20,0) (x = 30,20, -20, -60, -10,-60) L/O solve acceleration problems – list given information and assumptions in a chart. For objects in free fall acceleration is = g. determine what you are solving for – choose correct equation – WRITE IT DOWN – show substitution – circle answer with units. Examples Something speeds up from 20m/s to 30 m/s in 10 s. what is its displacement? (answer: 250 m) Something is moving at 20 m/s and is accelerated at 2 m/s2 for 10 s – what is final speed (ans: 40 m/s) Something is dropped and takes 10 seconds to hit the ground. How high was it dropped (ans: 490m) Something speeds up from 35 m/s to 70 m/s at a rate of 5 m/s2. How far does it travel? )ans: 440 m) L/O understand what was done in the labs

You will be asked questions about the Nspire acceleration lab and the Marble lab (#2). You may be

asked the purpose, discuss sources of error, make a labeled sketch or be given pretend data and asked

to calculate the same things we calculated in the labs.
