Which requires more work lifting a 25 kgbag of cement 10 meters vertically or lifting a 50 kgbag 5 meters vertically?
I think the formula is something like work (energy) is mass by height by gravity. as gravity is a constant, dont worry about it in comparison. 25*10 is 250 50*5 is 250. They require the same effort
How can you weigh things without equipment?
You can estimate the weight of things by lifting them with your hands, and you can compare it with standard weights - which weighs less - if you think that counts as "not using equipment". However, don't expect a great precision from this method.

Bernoulli's equation and an airplane's wing?
Bernoulli's equations explain 100% of the lifting force created by wings. But Newton's third law also explains 100% of the lifting force. This should not be suprising, since Bernoulli's equations are based on Newton's laws. Bernoulli and Newton are two different ways of explaining a complicated situation. Neither is more "right" than the other. If we choose one explanation while ignoring the other, then our understanding of flight will be incomplete. To be clearer... Bernoulli's equation describes the lifting force in terms of pressures applied to the wing surface. There are no other forces involved. If we know the pattern of pressures, then we know the lifting force. Yet the explanation of flight remains incomplete. Wings feel pressure because they change the motion of the surrounding "parcels" of air, and air has mass. If a wing applies a force which causes air to accelerate downwards, then by Newton's 2nd and 3rd laws, the wing must experience an equal upwards lifting force. If we know the acceleration of the air surrounding the wing, then we know the lifting force.

Muscular endurance
Does gender affect lifting capacity?
Somewhat. Men, in general, have a little more upper body strength than women. Certainly there are different types of lifting, and the fitness and strength of men and women vary from individual to individual.

How does cheerleading compare to other sports?
Cheerleading is different than other sports because cheering is the only sport that using the organized lifting or throwing of people
Why is stretching different from lifting weights?
Stretching focuses on lengthening and relaxing muscles to improve flexibility and range of motion without necessarily building strength or muscle mass. Lifting weights, on the other hand, is a form of resistance training aimed at building strength, muscle mass, and endurance by challenging the muscles with resistance and progressive overload. Both stretching and lifting weights are beneficial for overall fitness but target different aspects of physical performance.
