he line is stationary. **2. Which components are variable?** The angle and distance have to adjust to the weight so that it hits the line. **3. What would happen when the gun was fired at a 45o angle and there was no gravity.** **4. What kind of energy does the dart have when it is sitting cocked in the gun?** Potential energy because it has the capability to exert force. **5. What kind of energy does the dart show when it is moving?** High kinetic energy low potential energy because its potential energy is being transformed. **6. What happens to the energy when the dart hits the chalk board?** I is turned in to heat. **7. What kind of energy is it converted into?** Heat **8. Where did the energy come from to cock the gun?** The energy exerted by the human hand. **9. What kind of energy is that?** Chemical/biological energy <span style="font-family: Arial,Helvetica;">The less the degree of the angle is the shorter the distance. Judging from the graph my prediction looks to be true but more data is always needed. Darts and arrows need feathers to steady them. Here Bullets don't need feathers because of their size and the force acting upon does not have a kick-back because the machine or gun shoots in a straight line. <span style="font-family: Arial,Helvetica;">Increasing the mass which increases resistance and therefore shortening the range of the dart. <span style="font-family: Arial,Helvetica;">Gravity and velocity. =**<span style="font-family: Arial,Helvetica;">EXERCISE 2. SIMPLE LEVERS **= <span style="font-family: Arial,Helvetica;"> =**<span style="font-family: Arial,Helvetica;">EXERCISE 3. MAGI **= This magic trick uses the law of inertia. An object a rest remains at rest unless acted upon another force. When it comes to the second video, it failed because the man pulls upward first. This creates force that then acts upon the dishes in the same direction that the cloth was pulled. In order to pull of this trick you have to pull out towards so that all the energy flows in that direction. This way the dishes will not tip over and jump at you, but it might cause a slight movement of position (Forward).
 * EXERCISE 1: Speed, direction and gravity**
 * 1. Which components are controlled in this experiment?**
 * <span style="font-family: Arial,Helvetica;">10. WHAT IS YOUR PREDICTION FROM THE GRAPH? **
 * <span style="font-family: Arial,Helvetica;">11. DID THE TEST SHOW THE PREDICTION WAS CORRECT OR NOT? **
 * 12. Why do you think darts and arrows have "feathers", but bullets don't? (search online)**
 * <span style="font-family: Arial,Helvetica;">13. How does increasing the mass affect the range of the dart? **
 * <span style="font-family: Arial,Helvetica;">14. Which are the two forces at work on the darts? **
