Question

Derive the unit of force using the second law of motion. A force of 5 N produces an acceleration of 8 m s⁻² on a mass m₁ and an acceleration of 24 m s⁻² on a mass m₂. What acceleration would the same force provide if both the masses are tied together?

A body has a mass of 2 kg. When will the mass of the body change?

Read the following information and answer the questions based on information and related studied concepts. Sahil was driving the car at a very high speed to reach the hospital and he tried to drift the car. But the car slides from a ledge and falls to the ground in 2 seconds due to brake failure. Take acceleration due to gravity, g = 10 m/s².

Calculate the weight of an astronaut of mass 66 kg on the surface of the earth and on the surface of the moon. Also calculate the ratio of mass of astronaut on the surface of the earth and on the surface of the moon. Given that acceleration due to gravity on the surface of moon is one-sixth of that on the earth.
