Hypothesis: If a car is involved in a crash‚ a domino effect of reactions will occur. Background: The modern day automobile is a very complex piece of machinery that has a lot to do with the world of physics. Like every great invention‚ there was a beginning. For the automobile this beginning was in 1769. Nicolas Cugnot‚ a Frenchmen inventing for the French Army‚ came up with was first self-propelled‚ steam engined‚ three wheeled cart that was said to go as fast as walking speed. The next

can is that I would have a lot of rotational energy and momentum‚ the disadvantage is the car has more static inertia. If the car has more static inertia‚ then it will be harder for the can to roll backwards at the end of its run. The factors affecting the can’s net force (once the rubber band is unwound‚ but when the car still has momentum) are‚ force of gravity‚ normal force‚ KE‚ rubbing friction (into heat)‚ the re-winding of the rubber band‚ wind‚ and air resistance. The force of gravity and support

The Physics of Basketball Brittney LeBlanc Physics 122 Physics comes into play throughout our lives‚ in absolutely everything we do‚ especially in sports such as basketball. Although you do not need to be a physician to become a basketball player‚ if you understand the basic physics of basketball‚ it can be very beneficial to your game. Specifically‚ understanding the physics behind shooting‚ passing‚ and dribbling the basketball. A Canadian named‚ Dr. James Naismith‚ was instructed to create an

N force? [1.45×103 J] 3. A rope making an angle of 35.0o drags a 10.0 kg toolbox a horizontal distance of 20.0 m. The tension in the rope is 60.0 N and the constant friction force is 30.0 N. What work is done by the rope? What work is done by friction? What is the resultant work? What is the coefficient of friction between the toolbox and the floor? [983 J‚ -600 J‚ 383 J‚ 0.472] 4.

the spring. The Hooke’s Law is the magnitude of the force exerted by a spring is directly proportional to the distance the spring has moved from equilibrium. The springs that obeys the Hooke’s Law is called an ideal spring because it contains no friction externally or internally. The force constant is (k) the proportionality constant if a spring. The equation Fx=-kx. Fx representing the force exerted by the spring‚ x is the position of the spring relative to the equilibrium and k as the force constant

When the angle of an inclined plane changes‚ the normal force changes and so does the friction. In this lab‚ you will change the
