Physical Science: Learning about Force and Friction

We are investigating the force needed to move an object
 

How would you reduce the force needed to move an object?

Do you think more force would be needed on a rough surface ?

Or would more force would be needed with a heavier load?

We are investigating the effects of friction by experimenting with objects on a ramp.

What changes can we make so an object moves down a ramp faster?

Why do some objects move faster/farther?

Check the height of the ramp

Above is a picture of me and my partner, Sean, working a science experiment.  In this particular picture, we were putting a Matchbox car on a ramp, raising the ramp up in the air, measuring how high it was, and then letting the car go and seeing how far the car traveled.  Sean and I held the record for 385cm far and 15cm high.  It was a lot of fun testing the different cars and seeing how far they could go.  Our best car was a scale model of a 1959 Cadillac Eldorado, that car was flat out fast.  That was the car that we set the record with.  In the background, you can see Natasha Florian and Janique Berard trying their luck also at the experiment.  The experiment was the most fun experiment that we have had this whole school year.  I like science experiments because most of the time they are hands-on and you can intervene with what’s going on in the experiment.  This was a good experiment and I hope we try another experiment soon!        ~Cameron
