Classical mechanics
In projectile motion, this component remains constant throughout the flight, assuming air resistance is negligible.
What is the horizontal component of velocity?
In thermodynamics, this quantity represents the total internal energy of a system divided by its temperature.
What is entropy?
What is the difference between series and parallel circuits?
In a series circuit, components are connected end-to-end, so the same current flows through each component. In a parallel circuit, components are connected across the same two points, so each component has the same voltage across it, but different branches may have different currents.
Describe the difference between scalar and vector quantities, and give examples of each one
Scalar quantities are described by magnitude only and have no direction.
Examples: temperature, mass, and speed.
Vector quantities have both magnitude and direction. Examples: displacement, velocity, and force
The first woman to win a Nobel prize in physics is?
Who is Marie curie
This type of friction acts on objects at rest and must be overcome for an object to start moving.
What is static friction?
This property is defined as the heat required to change a substance's temperature by one degree Celsius per unit mass
.What is specific heat capacity?
What is the difference between a permanent magnet and an electromagnet?
A permanent magnet produces a constant magnetic field, while an electromagnet generates a magnetic field only when electric current flows through it.
What is the relationship between frequency, wavelength, and the speed of a wave?
speed = frequency * wavelength
As the frequency increases, the wavelength decreases, and vice versa, assuming the speed of the wave remains constant.
Wilhelm rontgen won the first Nobel prize in physics and it was for?
The discovery of X-rays
In the context of oscillatory motion, this term refers to the maximum displacement of an object from its equilibrium position
.What is the amplitude?
This law states that as the temperature of a perfect gas increases, its volume increases when pressure is held constant
.What is charle’s law?
How does grounding protect electrical devices and people from electric shocks?
Safe path for excess electrical current to flow into the Earth, preventing the buildup of voltage that could lead to electric shock or damage to devices.
What is the Doppler effect?
The Doppler effect refers to the change in frequency of a wave in relation to an observer moving relative to the wave source.
Who said, "I was ... in the patent office at Bern when all of a sudden a thought occurred to me: 'If a person falls freely, he will not feel his own weight.' I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation."
Who is Einstein?
