In MKS (SI units), mass is expressed in kilogram (Kg), length in meter (m) and time in second (s). What would be the units for the following?
a. Speed = distance/time b. Momentum = mass * speed
c. Kinetic energy = (1/2)*mass*speed2 d. Force = mass*acceleration
e. Work = Force * distance
Homework Answers
a. SPEED = dist/time = meter/sec. =m/s
b. Momentum = mass* speed = mass*dist/time = kg.m/sec.
c. Kinetic energy = (1/2)*mass*speed2 = kg*m2/s2 = Joule
d. Force = mass*acceleration = mass* velocity/time = kg*m/s.s = kg*m/s2 = Newton (N)
e. Work = Force. distance = kg*m*m/sec2 = kg.m2/s2 = Joule
