Where F = Force applied to the spring, k = spring constant, e = extension. Note: From the question, the force applied to the spring is the weight of the mass hung on it. Hence, F = mg..... Equation 2. Substitute equation 2 into equation 1. mg = ke. make k the subject of the equation. k = mg/e..... Equation 3. Given: m = 2.4 kg, e ...
Gravity - Math is Fun
http://electron6.phys.utk.edu/PhysicsProblems/Mechanics/1-Simple%20point%20particles/2nd%20law-friction.html WebThe weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. For an object in free fall, so that gravity is the only force acting on it, then the expression for weight follows from Newton's second law. flws target price
What is Hooke
WebNov 1, 2024 · Know the equation for normal force of an object at rest. When calculating an object's normal force when that object is at rest on a flat surface, use the formula: N = m * g In this equation, N refers to the normal force, m refers to the object's mass, and g refers to the acceleration of gravity. For an object sitting on a flat surface, with no outside forces at … WebMay 14, 2024 · a = acceleration. g = acceleration due to gravity ~= 9.8ms-2 on earth's surface. We start with your eq: ma = mg. Divide both sides by m: a = g. Yep. Don't think of g as a variable, but instead an exact value. Just like pi isn't a variable, it's a value, even though we write it as π instead of 3.14159265. WebAnswer (1 of 15): For the rest of the answer, neglect air resistance. Newtons second law gives that F_{net} = ma. Basically, the net force acting on a body is it’s mass times … flw stand for
