Study guide for Chapter 4 physics test 1
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
Free fall
Terminal velocity
Equilibrium
Net force
Weight
Normal force
Tension
Force due to gravity
Inertia
Newton’s 1st law of motion
Newton’s 2nd law of motion
Newton’s 3rd law of motion
L/O draw Free Body Diagrams – be able to correctly draw and label the forces on an object for a variety
of situations
Object sitting on a horizontal surface
Object pressed against a vertical surface
Object sliding or rolling up or down inclined planes
Objects falling freely with and without air resistance
Objects connected to cords or ropes
L/O solve 2nd law problems – list given information and assumptions in a chart. For objects in free fall
acceleration is = g. remember Fg = mg determine what you are solving for – choose correct equation –
WRITE IT DOWN – show substitution – circle answer with units.
Examples
A car with a mass of 3000 kg is accelerated at 7 m/s2. What is the net force on the car?
An elephant weighs 1,230,000 N. What is its mass? What is its weight in pounds?
A bus experiences a net force of 60,000 N while it is accelerated at 2m/s2. What is the mass of the bus?
What is the weight in pounds and Newtons of a 75 kg person?
L/O understand what was done in the labs
You will be asked questions about the Nspire 2nd law lab, broom ball lab, Barbie bungee lab, and the “g”
minilab. 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.
