# 3. Mass and Weight
# Scientists measure an object’s mass in kilograms and its weight in newtons. If you know the
# amount of mass of an object in kilograms, you can calculate its weight in newtons with the
# following formula:
# weight = mass * 9.8
#  Write a program that asks the user to enter an object’s mass, and then calculates its weight.
# If the object weighs more than 1,000 newtons, display a message indicating that it is too
# heavy. If the object weighs less than 10 newtons, display a message indicating that it is too
# light.

kg = float(input("Enter the mass of an object in kilograms: "))
newton = kg * 9.8


if newton > 1000:
    print("Your object is", newton, "newtons, it is too heavy.")
elif newton < 10:
    print("Your object is", newton, "newtons, it is too light.")
else:
    print("Your object is", newton, "newtons.")
