ramp
Matthew wants to push a 20 kg box up a ramp at a rate of 4 m/s2.
How much force is required of Matthew? Use: Force=Mass x Acceleration
Matthew wants to push a 20 kg box up a ramp at a rate of 4 m/s2.
Now that Matthew knows how much force is required to push his box, how much work will he have to do if the ramp is 7 meters long? Use Work=Force x Distance
Matthew wants to push a 20 kg box up a ramp at a rate of 4 m/s2.
What if the ramp was only 2 meters long? Use Work=Force x Distance
Matthew wants to push a 20 kg box up a ramp at a rate of 4 m/s2.
What generalization can you make about the distance over which you move an object and the amount of work that it takes to move that object?
Highway statistics show that accidents often happen when rain first begins to fall and the road is coated with a thin layer of oily water. Why are accidents likely under these conditions?
