Physics Motion and Energy Concepts

These flashcards cover key concepts on motion, energy, and electricity from the lecture notes.

What does the slope of a velocity vs time graph represent?

The slope represents acceleration, which is the rate of change of velocity.

What does a positive slope in a motion graph indicate?

A positive slope indicates that the object is accelerating.

What is the significance of the area under the curve in a motion graph?

The area under the curve represents the position.

What happens to the temperature of colder and warmer objects in heat conduction?

The colder object's temperature increases while the warmer object's temperature decreases.

According to Newton's 1st law, what happens to an object in motion or at rest?

An object in motion will stay in motion, and an object at rest will stay at rest until acted on by an outside force.

What is the equation representing Newton's 2nd law?

Net Force = mass * acceleration.

What is kinetic energy and its formula?

Kinetic energy is the energy an object has due to its motion, calculated using the formula KE = 1/2 mv^2.

What is the Conservation of Energy Theorem?

The Conservation of Energy Theorem states that energy cannot be created or destroyed, only transferred from one form to another.

What is the primary power source in an electrical circuit?

The battery serves as the primary power source, supplying input energy.

What unit is used to measure current in a circuit?

Current is measured in Amperes (Amps or A).
