Lab #109: One Dimensional Motion
Velocity as a Function of Time and Distance at Constant Acceleration
Objective:
To measure the constant acceleration of an object moving on an inclined plane by
several different analytical methods using two types of apparatus (photo gat and
motion sensor);
To get more familiar with onedimensional motion;
To apply Newton’s Second Law.
Background:
When an object moves with constant acceleration, its velocity as a function is given
by:
v
= (
v
0)^2 +
at;
Where v0 is the initial velocity (at t = 0), v is the velocity
of the object at x and a is the constant acceleration.
The velocity of the object as a function of distance is given by:
V^2 = (v0)^2 + 2a(xx0);
Where v0 is initial velocity (at x0), v is the
velocity of the object at x and a is the constant acceleration.
