Well, to lift 1 kilogram 1 meter straight up, you have to supply a force of 9.8 newtons (about 2.2 pounds) over that distance, which takes 9.8 joules of work. To get your ingot home, you need 750,000 times that. Put another way, 1 kilocalorie equals 4,186 joules. A kilocalorie is commonly called a Calorie (capital C) in nutrition; therefore, to ...

The Newton's second law of motion states that acceleration of an object is proportional to the net force F acting on it and inversely proportional to its mass m. It is expressed with the following equation: a = F / m. where: a [m/s²] is the acceleration of an object; F [N] is the force acting on an object; and. m [kg] is the mass of an object.

In that case, energy is extracted from the object, and the moving "required negative energy". Similarly, if it accelerates (perhaps a loaded spring gave it a push) then it will have more energy at the end than at the beginning, and it took work to move it. The amount of work in either of these cases would be

Friction theory with calculator and friction coefficients for combinations of materials like ice, aluminum, steel, graphite and many more. The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it. The frictional force can be expressed as. Ff = μ N (1)

To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity!

The following formula is used to calculate the braking force of a car given a speed, weight, and stopping distance. F = (.5*m*v^2)/d F = (.5 ∗ m ∗ v2)/d. Where F is the required force to stop in distance d. m is the mass of the car. v is the velocity of the car before braking. d is the stopping distance.

So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The resistance per wheel is 14.1 lbs. Since the truck has four wheels, the total force to move (sustained motion) the truck is 14.1 x 4 = 56.4 lbs. Wheel diameter plays a significant role in the force required to move a load. In the example above, using a 16-in. diameter wheel (with a radius of 8 in.) would halve the required force.
