- Is there a difference between Weight and Force of Gravity?
Weight is the force experienced by a body due to the gravity of the earth, a planet, a particle, or another body The Force of gravity is the force that brings about weight
- Why do we treat weight as acting on the object?
The "weight" acting on the person is the downward force of gravity on the person The free body diagram of the person shows an equal and opposite reaction by the floor for equilibrium
- newtonian mechanics - Why normal force is greater than weight . . .
3 The explanation of the banking angle of the road is said to be that one part of the normal force exerted by the road on a moving object neutralizes the object's weight and another part is providing the centripetal force necessary to turn the object in a circular path So the normal force is greater than the weight of the object
- What is the difference between weight and mass?
Weight is the force with which gravity pulls on a mass Maybe the simplest way to explain the difference is that on the Moon or on Mars, your weight is reduced because gravity is weaker there, but your mass is still the same
- How does $m$ fit into the equation for weight? - Physics Stack Exchange
A body is under a force in earth's gravity $$\mathbf {F}=\mathbf {F_g}-\mathbf {R}$$ where $\mathbf {R}$ is the reaction to the mass imparted by the surface on which it is resting and $\mathbf {F_g}$, is the force imparted by the mass on that surface
- Does lifting an object from rest require a force greater than its weight?
The work gravity does equals its force time the upward displacement of the object, no matter what the upward force is The work done by gravity is negative because its force is opposite the direction of motion
- newtonian mechanics - The normal force in an elevator thats . . .
You are confusing weight (- force due to gravity) with mass The persons mass remains constant at all times, so to their weight due to gravity but the floor has to provide the extra push needed to accelerate the person upwards or provide less force if the lift is accelerating downwards As the lift is accelerating upwards the lift has stop your mass pushing down trough it In other words it’s
- Why should the normal force equal the weight of an object when the . . .
In the context of newtonian mechanics, I am investigating whether the normal force exerted by the surface upon an object must always equal the weight of the object mg (i e , the gravitational force applied by the object and earth upon one another, as per the 3rd Law), provided that the surface on which the object stands is flat
