The lab-

The goal of the lab was to figure out how velocity changes when there is a simple force acting on an object.

Acceleration is the change in velocity per change in time.

This experiment was using a track and cart but instead of figuring out the position and time, we were figuring out the acceleration to then being able to make velocity change.  This lab is sorta similar to this recent lab I did with a track and a cart, this time we allowed the track to be a bit unbalance to allow gravity be the force to increase the velocity.

The four times that I had to calculate the velocity is the amount of seconds which were 1 through 4 seconds as well as in between such as 1.20 or 2.20.

Calculating Acceleration-

The equation that allows me to calculate acceleration in any situation is the change in velocity divided by the change in time.

When calculating 3 times, what I got was 1.0, 0.5, and 1.0.

The 3 acceleration were similar.

The average acceleration was 0.833cm/secs.

Claim #1-

When there was a simple force acting on an object, the velocity didn’t change much in the same amount or in other words, the acceleration was constant.

Making Predictions-

If the car accelerates 30 mph per seconds for 5 seconds, the care would increase by 150mph.

The equation that lets me calculate change in velocity on acceleration is, acceleration times change in time.

If the car was already going 100mph, the car would be going 250mph.

The equation that lets me calculate the final velocity is, start velocity plus the change in velocity.
