One of the four fundamental physical forces, gravity influences every engineering enterprise humans have ever undertaken, especially in the realm of economics. Being able to calculate the force of gravity and solve related problems is a basic and essential skill in introductory physical science courses...
Here's a real-world example of when you might need to convert from volume to weight: Imagine that your friend just bought a house with a big back yard and wants to put in a garden. She's ordered two cubic meters of topsoil and is wondering how much all that dirt will weigh. You a...
In order to use this law to calculate acceleration, we must apply it in conjunction with Newton's Second Law, F=ma. To determine the acceleration of a spring-mass system we use a=kxm where a is acceleration in meters per second squared, k is the spring constant in Newtons per...
Step 2: Use the formula for universal gravitation to calculate the force between the objects. We will apply Newton's law of universal gravitation to calculate the force between them: $$F_g = \dfrac{Gm_1m_2}{r^2} = \dfrac{(6.67 \times 10^{-11}\ \rm{N\cdot m^2/k...
Using Density to Calculate Mass or Volume of a Sphere Suppose you have a cannonball made completely of iron. You can look up the density of iron in a table: 7.8 g/cm3. You weigh the cannonball and find it weighs 20 lbs. You now have enough information to calculate its volume, so ju...

More Great Links Bending Spacetime in the Basement (how to repeat the Cavendish Experiment to calculate the gravitational constant G) Science Daily: Discovery Of 'Cosmic ...
The hardest part to work out when you calculate falling object forces is the distance traveled. You can estimate this to come up with an answer, but there are some situations where you can put together a firmer figure. If the object deforms when it makes impact – a piece of fruit that...
What is the weight (in Newtons) of an object with a mass of 25 kg on the surface of the Earth?. The weight of an astronaut plus his spacesuit on the Moon is only 270 N. A. How much do they weigh on Earth, in Newtons, assuming the acceleration due t...
Is force measured in newtons? How to calculate force from momentum? Forces of 3.0 N and 1.0 N act on a 6.0 kg mass as shown below. What is the acceleration of the 6.0 kg mass? What is the difference between magnitude of a force and the force? A net force of 16 N causes ...
