Study guide for Chapter 4 physics test 1

1 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

2 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.

3 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.
