Cart

To make our Physics class interesting  and to learn more we took a cart the last Wednesday 20/ 2013
With that cart we want to apply the second law of motion, as we know that the  second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
The mass of our cart was 273.1 g

 

Then we tried to measured the force, we used a special tool named Spring Scale with this tool we have to  pulled the kart to measured the force, were vere accurate with the measured. We repeated this 3 times with different mass.

Then we recorded our 3 trials that we did and we obtain differents results but similar, we already have the force and the mass so we isolate for acceleration and we obtain acceleration. We can observed in this table

Trials	Force	Mass	Acceleration
Trial1	2.8 N	1.23 kg	2.26 m/s
Trial2	3.7N	1.73 kg	2.13 m/s
Trial3	4N	1.93 kg	2.06 m/s

 Data: the accelaration is meters per second square
