Balance the middle of the string over a tall solid object so the cups can hang freely. The weight of an object is calculated by multiplying the volume by the density of the material. Local gravity acting on object enter the acceleration due to gravity for your geographical location in metres per second per second ms 2. The equation used to calculate the weight of an object is f ma. To start tie string to the top of 1 cup then tie the end of the string to the top of another cup. To determine the volume of a sphere you have to take the diamater to the power of 3 and multiply it to pi as well as 16.
Find the equation that needs to be used to solve the problem. While a scale is the most accurate way to find the weight of an object you can get an approximation by using a handmade balance. In this case weve measured the length between the tip of the cockpit and the back of the last coach. To calculated the volume of a cube take the edge length of the cube to the power of 3. The local gravity is dependent on several factors such as latitude height above sea level local geological density etc. In general the gravitational potential energy gpe arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space.
An object of mass 50 kg has a gpe of 9800 j find the height of the object. In todays entry were going to talk about length width and height as tools to find the dimensions of an object. Length is a linear measurement which means we can only use it to measure the distance separating two points. Weight calculator mass calculator. Height 9800 50x 98 20 m. F is the force in newtons m is the mass in grams and a is the acceleration due to gravity.
Enter the mass of the object that you wish to determine the gravitational weight.
