what you need to know:
To accomplish your mission, you will need to understand what force is. It can be a challenging idea to get your head around since much of the time, we cannot see forces in action. What we can see is the result of forces at work, like your pencil dropping to the floor when it rolls off of your desk. Humans use force everyday to accomplish 'work'. Forces are also acting upon you every second of everyday. On any mission, knowing what you are up against is essential for success, so you will need to familiarize yourself with the facts about forces. Read on to learn more.
What causes objects to move? In the lunchroom you pull a chair away from a table before you sit down and push it back under the table when you leave. You exert force on the chair and cause it to move.
Force:
In its simplest terms, a force is a push or a pull that influences the way that an object moves. Forces are most often invisible, but they can be very powerful.
what forces can do:
A force can do the following things:
- put an object into motion
-stop an object that was in motion
- change an object's speed (it can speed it up or slow it down)
- change an object's direction
- put an object into motion
-stop an object that was in motion
- change an object's speed (it can speed it up or slow it down)
- change an object's direction
Try it out!
Use this virtual simulation to explore with small and large forces. You will try out pulling and pushing to make an object move. You will also need to place objects in the moving item's path to determine what happens. As this is just a simulation, the danger level is not too high. When you feel like you have gathered enough information, test yourself using the built in quiz feature. Good luck! Click on the picture below when you feel ready to start the simulation.
Slope & Load:
How an object moves can be influenced by both slope and load. Slope refers to the slant of the surface that the object is being moved along and the load is the amount of weight or mass being supported or carried. Try out this virtual experiment using force, slope and load. What conclusions can you draw about the relationship between slope and load? Click on the picture below to follow the hidden link. Conduct the experiment and then take the quiz when you feel ready to.
