LAB 5: Acceleration
OBJECTIVE: The objective of this experiment is to calculate the acceleration of an object rolling
down an inclined plane.
PROCEDURE: .
1.
Set up a ramp as shown in Figure 1. Depending on the length of the board mark
off three distances
Waves
Introduction: In this laboratory you will investigate aspects of waves on strings and sound.
Part 1: String Waves:
1. On the apparatus at your table set up a piece of twine with a mass of 250g hanging from its end. Adjust the
frequency of the oscill
Oscillations
Introduction: In this laboratory you will investigate the oscillatory properties of a pendulum and mass-spring
system.
Pendulum:
1. Measure 50cm of string and measure the period for 4 pendula of different mass. For each pendulum
determine the
Projectile Motion
Recall that a projectile is an object that is launched (projected) with some velocity into the air
and subsequently moves under the influence of gravity. In this laboratory you will investigate
several aspects of such motion. In the foll
Momentum and Energy
A. Consider the following problem: A ball of mass m rolls down a curved track onto a horizontal surface as
shown in the figure. Assume the ball is originally at height h above the horizontal surface.
1) Is the acceleration of the ball
Measurement
Most of you have probably had to make various kinds of measurements; perhaps buying mail-order clothes or
determining how much fabric is necessary for draperies. You might have also confronted the possibility of
arriving at a measurement that
Newtons Laws
And Friction
In this laboratory you will investigate some aspects of Newtons Laws and friction we have
discussed in class.
Friction:
a) Consider a block being pulled by a string on a horizontal surface with friction as shown
in the figure. As
Vectors
Introduction: As we have discussed in class vectors (arrows) add with one another just like successive straightline displacements. In this lab you will consider the addition of several vectors and compare your results with

Ques%on
Michael is going to the store 6 miles away. He rides his bike
at 12 mph for the rst half of the trip, then walks at 4 mph
for the remainder.
Michaels average speed for the trip
1. A bird, accelerating from rest at a constant rate, experiences a displacement of 28 m in
11 s. What is the average velocity?
2. A railroad train travels forward along a straight track at 80.0 m/s for 1 000 m and then
travels at 50.0 m/s for the next 1
Force causes Acceleration
Acceleration is directly proportional to net force
To increase the acceleration of an object, increase the net force acting on it
Acceleration ~ net force
Directly proportional to each other
Force of Friction
Depends on the kinds
