PRELAB: FORCE AND MOTION
1. What is the difference between a linear and a proportional relationship?
Linear: y = mx + b
proportional: y = mx
Linear is a straight line with a slope of m and a y-intercept of b. Proportional
PRELAB: TORQUE AND EQUILIBRIUM
Describe the condition required for a point particle to be in equilibrium.
The torque must be equal to zero
The net force must be equal to zero
A 10 N force is applied at a 20 angle to
Consider the block moving from x = 0 to x = +2.7 m (the spring is stretching.)
1. Sketch rough graphs of x-t, v-t, and a-t. Describe the key features of your graphs and explain why you

PRELAB: CREATING MATHEMATICAL MODELS OF MOTION
For what kind of motion is the relationship between velocity and time linear? For this kind of
motion, what will be the form of the relationship between position and time?
Force Day 5: Friction
A 5.0 kg block rests on a table. The coefficient of static friction between
the block and the table is 0.60. If you push on it with a 20 N horizontal
force and it doesnt budge, how much is the static frictional force on the

LAB: FORCE, MASS, AND ACCELERATION
Qualitatively and quantitatively reason with definition of acceleration.
Carry out proportional reasoning with Newtons second law.
Reason qualitatively with Newton
Newtons third law: If object A exerts a force on object B, the object B
exerts a force on object A, of the same magnitude but opposite direction.

Bobsled. A 170 kg boblsed must reach a speed of 10 m/s during the
allowed 50 m push-off stretch in order to be competitive. The
friction force is about 90 N, and well neglect drag in this example.
