The objective of this weeks lab was to explore Newton’s second law which implores the
conservation of energy and motion.
Newtons second law is demonstrated by the
following equation:
Σ F = mass x acceleration
To observe this law, we used a cart with certain mass acting on it at all times.
At one
point in time the mass was falling and pulling the cart and as mass was taken from the
pulling mass it was placed on the cart.
This was done so that the same mass was acting
upon the total system at all times.
By observing
the time and velocity at which the cart
passed through each photogate we were able to determine the acceleration at which the
cart was traveling.
To find acceleration, the following equation was used:
.
a = Δv
Δt
After finding the acceleration and the force, the two were plotted against each other and
the resulting trendline equation was used to determine the experimental mass of the cart.
