Understanding Gravity and Weight

The video tutorial explains the difference between mass and weight, using examples like a bag of sugar to illustrate the concepts. It discusses how weight varies on different planets due to gravity and provides calculations for weight using the formula W = mg. The tutorial also covers the effects of gravity on objects and concludes with a reference to Newton's apple, emphasizing that while mass remains constant, weight can change depending on gravitational forces.
