Question

Write True or False:

1. The force required to lift a mass 1 kg in vertically upward direction is called newton.

2. Streamlining reduces the friction between a body and a fluid.

Please help me to solve this physics true or false. ​

Answer 1

Explanation:

F (Newton)= m (kg) * g (m/s^2) The units in this expression are fine, because the by definition 1 N = 1 kg m/s^2. So, if you take a mass of 1 kg, and lift it vertically with your arm, then your arm will be pulling the mass with a force of F = 1 kg * 9.8 m/s^2 = 9.8 N.

A streamlined body is a shape that decreases the friction drag between a fluid, such as air and water, and an object that passes through that fluid. Drag is the force which reduces the speed of the motion.
