Frequently Asked Questions

Q1. What is g in physics?

In physics, g represents the acceleration due to gravity. It is a constant value of approximately 9.81 m/s^2 and represents the rate at which objects fall toward the Earth.

Q2. What is the impulse in physics?

In physics, impulse is the change in momentum of an object that occurs when a force is applied to it for a specific duration of time. It is a vector quantity calculated by multiplying the force by the time interval over which it acts. Impulse is crucial in understanding collisions and other situations where forces act over a short period of time.
