The force pulling downwards on the pan and weights is the force of gravity. This force is acting on all objects with mass towards the center of the Earth.
The main forces acting on a weightlifter lifting weights are the gravitational force pulling the lifter and weights downward, the normal force supporting the lifter from the ground, and the force exerted by the lifter to lift the weights against gravity. Additionally, there may be frictional forces between the lifter's body and the weights or the ground.
the congress can fix standards for weights
If you haven't lifted weights before a month of doing so can really improve your muscular appearance.
doing push-ups; using your own body as the weights
by doing resistance training with weights
gravity
force of friction in air and force of gravity downward.
No, they would both fall at the same speed.
By doing cardio activities and lifting weights.
No, the other way around: all weights are forces. The word "weight" is used for one specific type of force: the force of attraction due to gravity.
The forces acting on the weight lifter and the weights are balanced when the weight lifter is holding the weights stationary. The force exerted by the weight lifter is equal and opposite to the force of gravity acting on the weights.
