What experiment can you use for force?
A lab used to determine and analyze Newton's second law, the relationship between force, mass, and acceleration, is one in which you are able to effectively determine one of the three variables in Newton's second law. The lab consists of a track(for a cart) on a flat surface, a cart, and weights to put on the cart. With this lab you are also able to determine the relationship between Force and acceleration, and acceleration and mass.To find acceleration you will need to measure the time as well as the distance, so you will need a yard stick as well. The experimental procedure includes:
1. Put the track on a flat surface and gather all needed materials, including a stopwatch, cart, and weights.
2. Put the cart in the position, and measure the distance where it will go. This distance will be used to calculate velocity.
3. Push the cart with no weights attached and measure time. Divide the distance by the time to get acceleration.
4. Once acceleration is acquired, and cart is weighed to get the mass, you will be able to calculate force.
5. Repeat procedure several times while adding more mass each time to find out the relationship between force and acceleration as well as acceleration as mass.
An important result of this lab was that we discovered that acceleration decreases as mass increases. We also discovered that as force goes up, acceleration will go up as well. We also got to see first hand that as the cart went along the track, it did not stop unless acted upon by another force, which proved Newton's first law as well.

Real Life Examples
Forces are involved in our every day lives, and occur all around us as well. One example is a banner hanging from the top of a stadium. This not only deals with tension, but it could deal with angular tensions as well. If the workers decide to hang the banner at an angle(which is inefficient), they will have to deal with angular tension as well. Another example is moving boxes. The lifters have to decide not only the most efficient way to move boxes into a truck, but which requires the lest amount of force to do so. When creating cars, the mechanics had to think of something that requires the least amount of friction, and could get people home efficiently and safely. Forces are involved in many parts of our lives, whether its tension or friction, we use these every day even if we do not know it.
