Terminal velocity in physics is the highest constant speed at which a falling body can travel when it is moving through a fluid, like water or air. While an object is falling, gravity attracts it downwards, and it accelerates. But as it gains speed, air resistance or drag due to the fluid also increases. At some point, the air resistance upwards equals the force of gravity downwards. By now, the two velocities are equal, and the object no longer speeds up. Rather, it keeps falling with a constant, invariable velocity. This velocity is called the terminal velocity. For instance, when a skydiver leaps from an airplane, they accelerate and move faster and faster initially, but after some time, they stabilize at a velocity where the resistance of the air equals their weight, and they keep falling at that same speed until they deploy their parachute. Terminal velocity is based on a number of factors such as the mass, shape, and surface area of the object, and the density of the fluid in which it is descending.

Nutrition is like giving your body the right kind of food it needs to grow, stay healthy, and work properly. It's like fuel for your body. Just like a car needs good fuel to run smoothly, your body needs healthy food to keep going strong. Eating fruits, vegetables, proteins like meat or beans, and grains like bread or rice helps your body stay strong and fight off sickness. So, think of nutrition as giving your body the right kind of food to be its best self!
