Friction is a nonconservative force. Therefore work done against friction cannot be stored as potential energy and later converted back to kinetic the way work against gravity can.
Gravity always pulls objects such as a desk, book or person down. Thus, when you jump, gravity causes you to land on the ground. Friction, however, doesn't pull objects down. ... Instead friction occurs when something like a machine or individual pulls a sliding object in the opposite direction of another object.
Friction and gravity exist in every aspect of a person’s life. For example, almost every movement you make, such as walking and running, involves friction. When you throw a ball up, gravity causes the ball to fall down. A person sliding a book across a table creates friction. Nevertheless, differences between gravity and friction also exist. Force affects gravity and friction in different ways.
Answer:
294 W
Explanation:
Electrical power: This can be defined as the rate at which electrical energy is used or dissipated. The S.I unit of electrical power is Watt(W).
The expression of electrical power is given as,
P = I²R................... Equation 1
Where P = power, I = current, R = Resistance.
Given: I = 7 A, R = 6 Ω
Substitute into equation 1
P = (7)²(6)
P = 294 W.
Hence the power power absorbed by the resistor is 294 W
The impact of the heavy stone would produce waves with a higher amplitude because the stone would pick up more speed while falling.
