Questions 1. Explain how the use of the sloping chipboard ‘compensates for friction’ The use of the sloping chipboard compensates for the friction in the experiment as it increases the acceleration on the cart due to gravity and if placed on the right angle it will correctly compensate for the speed lost in friction. 2. Why should the amount of Velcro used be just enough to make the trolleys adhere after the collision? The amount of Velcro used should be enough to keep the trolleys together

The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. <br> <br>Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring‚ which have raceways‚ or slots‚ grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types

Our goal or task for our Rube Goldberg project was to feed the money pig. For our first step a ball rolled down an inclined plane and hit ten dominios. Then the dominios hit a marble for our second step. For our third step the marble rolled off a table and went through a funnel and triggered a mouse trap. In our fourth step the mouse trap went off and a popsicle stick fell off an inclined plane and made a golf ball to roll down it. For our fifth step the golf ball hit another ball on a table. In

The goal of this project was to build a mousetrap powered car that would be able to travel in a straight line for five meters. The team of partners could build a car designed to either travel a far distance or focus on speed and travel the five meters in the quickest amount of time. A mousetrap car works when one end of a string is tied to the arm of the mousetrap. The other end of the string would then be tied around the axle‚ this would stretch the mousetraps string which would provide stored energy

The momentum from the club is then transferred from the club‚ to the ball. When the ball is in the air‚ it is moving at a constant velocity but is being acted upon by friction‚ which would be the air and gravity. Over a certain amount of time‚ the ball will eventually hit the ground‚ depending on its momentum and how much friction is acted on it. Another example of physical in the real world would be The Law of Inertia. This law is the idea of the tendency of an object to resist any change in

this experiment is to determine the relationship between pressure head‚ velocity head‚ and static head and compare it with Bernoulli’s Theorem. The total head of flowing liquid between two points remain s constant provided there is no loss due to friction no gain due to application of outside work between the two points. So basically the apparatus used for this experiment consist of a venture tube with different diameter at certain part‚ 8 tubes of water manometer‚ a rotameter‚ stainless steel tube

remain at rest until a force acts upon it. Yet‚ it will keep going at a constant speed unless another force overpowers it. When a force is applied it doesn’t necessarily have to be one force‚ it can be multiple. Those forces could include gravity‚ friction‚ and your own. In order for this law to be applied to an object‚ it must be in equilibrium. An object is only equilibrium if the vector sum of all forces equals zero. With these forces & objects also experience acceleration explaining the connection
