What is Newton's second law of motion as typically tested in the ESAT Physics section?
Answer: F = ma
Newton's second law states that the net force equals mass multiplied by acceleration (F = ma).
In an ESAT physics problem, a 2 kg object accelerates at 5 m/s². What net force acts on it?
Answer: 10 N
F = ma = 2 kg × 5 m/s² = 10 N.
Which of the following describes the work-energy theorem?
Answer: Net work done on an object equals its change in kinetic energy
The work-energy theorem states W_net = ΔKE = ½mv² - ½mu².
What is the SI unit of electric charge?
Answer: Coulomb (C)
The SI unit of electric charge is the coulomb (C), equal to one ampere-second.
A wave has frequency 500 Hz and wavelength 0.68 m. What is its speed?
Answer: 340 m/s
v = fλ = 500 × 0.68 = 340 m/s, which is the speed of sound in air.
In the ESAT Physics component, Ohm's Law is expressed as:
Answer: V = IR
Ohm's Law states that voltage (V) equals current (I) multiplied by resistance (R).
