It is called work. If you lift a rock one meter you are doing work. When you stop lifting so work stops even though your muscles are working to keep the rock at that hight.

When only mechanical energy acts on an object what is conserved?
gravity
How does using a ramp make lifting a heavy object easier?
You get mechanical advantage by the slope of the ramp. You move the object horizontally and raise the object slowly as you do so.
The energy that is given to an object that is lifted?
Potential energy is the energy of location. Gravitational potential energy is given by lifting an object, and is defined by the equation Ep = mgh, or mass * acceleration due to gravity * height.
What force in an object resists stretching or pressing?
Propelling force
What is meant by rigid and solid?
An object which is rigid resists bending and flexing. An object which is solid is not hollow.
When only acts on an object mechanical energy is conservered?
gravity
When only mechanical energy acts on an object what is conserved?
gravity
Which two forces of a result is the orbit of the planet?
Gravity, which pulls an object inward, and inertia, which resists gravity. They combine to form a more-or-less circular orbit.
Differentiate between force of gravity and force of friction?
F(gravity) pulls a movable object toward the center of mass (generally the Earth). F(friction) resists F(gravity) when the object is scraping against something that is solidly attached to the mass (Earth).
How does using a ramp make lifting a heavy object easier?
You get mechanical advantage by the slope of the ramp. You move the object horizontally and raise the object slowly as you do so.
Where should your center of gravity be in relationship to your base of support when lifting an object?
high above the support base
How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
When a force is applied that moves an object in the direction of the applied force is gravity done?
Gravity is indeed a force, but only one out of many. magnetic, frictional, mechanical ... . When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.
How do you calculate static?
A static load is the mechanical force applied to an object as a result of both gravity's push and the weight of the object. It can be calculated by averaging out the two numbers.
What is potential energy depended on?
The potential energy of a mechanical object in relation to gravity is dependent on the mass of the object, and the height of the object above the earth. Generally represented by this equation: PE=mgh
When an object resists on any change in motion?
Inertia
How do you calculate static load?
A static load is the mechanical force applied to an object as a result of both gravity's push and the weight of the object. It can be calculated by averaging out the two numbers.
