NEWTON’S 2ND

LAW

Newton’s 2nd Law

Newton’s 2nd Law – Acceleration of an object increases when you increase force & decreases when you increase mass.

Equations of Inertia Distance/time=speed Final velocity – initial

velocity/time=acceleration Acceleration x mass=force

LAB

Objective

The objective of this experiment is find how the force and acceleration of an object change when you increase and decrease the mass.

Materials

1 milk jug Water Scale Stopwatch 1 volunteer Meter stick

Procedure Measure and mark 5 meters on the floor Weigh the empty milk jug Push the empty jug first, and start the time

when you push it and stop the time when it crosses the 5 meter mark.

Find the velocity of the milk jug (distance/time)

Find its acceleration (final velocity - initial velocity/time)

Find its force (acceleration x mass) Repeat steps 2-6 with the jug filled with

water Compare the differences in force and

acceleration of the two jugs

Conclusion

In this experiment we found that when you change the mass, both the force and acceleration of an object are changed. A change in any one of these factors can change the outcome.
