To reduce angular speed on a freely rotating platform, a person should spread their hands outwards. This increases the moment of inertia, causing the rotational speed to decrease according to the conservation of angular momentum.
The force of Earth’s gravity acting on a body of mass 1 kg is calculated using the formula F = m x g, where g is the acceleration due to gravity (9.8 m/s²). Therefore, the force is 1 kg x ...
On removing butter from milk, the density of milk increases. This is because butter is less dense than milk. When butter is removed, the remaining liquid is denser than the original mixture.
Shock absorbers are usually made of steel because its elasticity is high. High elasticity allows steel to absorb and dissipate energy efficiently, making it ideal for withstanding the repeated stress and strain experienced in shock absorption.
