Sample Questions and Answers:
-
What is the unit of force in physics?

A rocket works based on Newton’s third law of motion: for every action, there is an equal and opposite reaction. The expulsion of gas from the rocket creates thrust, propelling it forward. -
What is thermal conductivity?
Thermal conductivity is the ability of a material to conduct heat. Metals typically have high thermal conductivity, while insulators like wood and plastic have low thermal conductivity. -
What is the effect of temperature on resistance?
As the temperature of a conductor increases, its resistance typically increases as well. This is because the atoms in the conductor vibrate more, hindering the flow of electrons. -
