How do objects and substances have kinetic energy??<br><br> I need help ASAP!!
9966 [12]

Objects and substances in motion have Kinetic Energy.

Explanation:

Kinetic Energy is the motion of objects, substances, molecules, atoms .

Whenever an object starts to move, it is in motion. Kinetic Energy is generated, when the object moves and its potential energy gets dropped with the movement. Kinetic Energy is found in every object that moves.

The Kinetic Energy of an object depends both on its mass and its speed. Kinetic Energy increases as mass and speed are increased.

Example:  By using the wind flow from wind turbines, the Kinetic energy in the wind can be transformed to generate electricity by using generators.

Class II levers like ankles and wheelbarrows are useful because they provide mechanical advantage, by amplifying the input force
marusya05 [52]

Answer:

The solution and the explanation are in the Explanation section.

Explanation:

According to the diagram that is in the attached image, the EFFORT force at point A and the load is at O point. The torque due to weight is:

TA = W * (a * cosθ)

The torque due to effort at C point is:

TC = E * (b * cosθ)

The net torque is equal to 0, we have:

Tnet = 0

W * (a * cosθ) - E * (b * cosθ) = 0

E=W\frac{a}{b}

From the figure, you can observe that a/b < 1, thus E < W
