Suppose that 4 Joules of work is needed to stretch a spring from its natural length of 13 cm to a length of 3 cm. How far (in meters) beyond its natural length would a force of 35 N keep the s...
What is the power delivered by a motor lifting an elevator weighing 1250 kg up 89 floors at 16.8 meters per second? A 22.5 kg box (m_1) rests on a table. What is the weight of the box? A person can lift 45 kg ( approx 100 lb). Using specific gravity as 10.17, how many...
Force equals mass times What is the meaning of tension force? Give examples. A center seeking force related to acceleration is what type of force? What force is necessary to lift a rock weighing 150 kg by using a metal bar that is 2.0 meters long if the fulcrum is placed 30 cm from ...
When an object fall towards the earth then the object accelerates at a constant rate and that constant rate of acceleration is known as acceleration due to gravity which is equal to9.81m/s2. When the object falls only under the influence of acceleration due to gravity then...
The metric units for force are newtons, those for distance are meters and those for work are newton-meters, or joules. Energy is the capacity for doing work, and it is also expressed in joules. Kinetic and Potential Energy An object in motion possesses its energy of movement, which is equ...
where you have Force, where he’s putting a certain amount of force, Force is Mass X Acceleration, which is measured in Newtons. So, you have 700 Newtons, and he moves it two meters. So, 700 times two would be 1400 Joules. Joules are actually meters in Newtons anyway, not to get ...

This is read as, force equals mass times acceleration. In standard international units (SI units) mass is given in kilograms (kg), acceleration is given in meters per second per second (m/s2), and force is given in Newtons (N). Abbreviated as N, a Newton is defined as the force ...
The Greek symbol ∆, or delta, means "change" or "difference" by convention in physics and math. In addition, you can verify that pressure times volume gives units of work; pressure is measured in newtons/m2, while volume may be expressed in m3. ...
