Energy and Oscillations

These flashcards cover key concepts related to energy, oscillations, simple machines, work, power, and kinetic energy as discussed in the lecture.

What is the relationship between force and energy in the context of oscillations?

The force does work to increase the ball’s energy, affecting its motion.

What is a simple machine?

A device that multiplies the effect of an applied force.

What is the mechanical advantage of a simple machine?

The ratio of the output force to the input force.

What is the formula to calculate work?

Work = Force × Distance (W = F d).

What are the units for measuring work?

1 Joule (J) is equivalent to 1 Newton meter (Nm).

What does power measure?

Power is the rate of doing work.

How do you calculate power?

Power = Work divided by Time (P = W / t).

What is kinetic energy?

The energy associated with an object’s motion.

What happens when work is done on an object?

It increases the object's kinetic energy.

What is negative work?

Work done by a force acting in a direction opposite to the object’s motion.
