Physics 111 Lab #1:
Kinematics
1-dimensional motion with and without the influence
of gravity will be studied by varying the inclination angle of the cart
track (Lecture 2).
Key Activities:
1-Dimensional
Uniform Velocity
1-dimensional motion experiments
involving a cart on a flat "frictionless" track will be used to study the
relationship between displacement, velocity, and acceleration under
various circumstances, for example when the "particle" has a uniform
velocity (Lecture 1).
1-Dimensional
Uniform Acceleration
The relationship between
displacement, velocity, and acceleration will also be explored for
situations in which the cart is experiencing uniform acceleration
(Lectures 1 and
2).
A cart on a track having an inclination angle Ø
experiences a component of the gravitational acceleration. This figure
illustrates typical plots of the cart's displacement (top), velocity
(middle), and acceleration (bottom) for a cart moving up and down an
inclined ramp (Lecture 2).
What's happening?
Estimate of the
Acceleration Due to Gravity, g
By measuring the cart's
acceleration, geff = gsinØ, for various inclination angles,
Ø, an estimate of the gravitational acceleration, g, can be obtained
(Lectures 1 and
2).
