Answer the given worksheet
Answers
Answer:
1.work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.
2.energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed
3.energy which a body possesses by virtue of being in motion.
4.the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Answer:
1 In physics, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, it is often represented as the product of force and displacement.
2 the ability to be very active or do a lot of work without getting tired
बहुत सक्रिय रहने की या बिना थके अत्यधिक श्रम करने की क्षमता; ऊर्जा
3 In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
4 Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
