4. What does it feel like to go on a roundabout on a playground? Draw a diagram to explain how the water stays in the bucket Include the forces on the bucket Forces on a swinging bucket
5. The turn table demo How long will these objects stay on? What forces are acting on these objects? Where is the best place to put the object to make it fly off the turntable 1. When a car turns a corner it can sometimes skid. Explain why, using the words acceleration, velocity, friction, force and mass .
6. Answer these Questions Bends in a roller coaster are always banked and when the train rounds a bend you feel heavier. For each of these situations: (a) what happens to your weight (b) what happens to the force on you from your seat (c) what is happening to your velocity (d) why do you feel heavier? A roller coaster train loops a loop so that at the top of the loop the downward acceleration is 12 m/s 2 . The weight of the roller coaster is 80 kN. (a) What two forces are acting on the train? (b) What is the mass of the train? (c) What is the total force on the train? (d) What is the downward force of the track on the train? (e) What is the upward force of the train on the track? Force = mass x acceleration F = ma
7. Draw a diagram of the Earth going around the sun Label the forces Remember the Earth must have an initial velocity If a satellite is always falling towards the Earth why does it never get any closer?
8. Homework Here are some calculations for you to do, it should show me how well you understand what I have taught you Have a go Remember to use the equations you have written down.
