(using squats for the sake of explanation)
The lifter exerts an action force on the weight, which is in the opposite direction to gravity. The lifters shoulders also experience the reaction force (from the weight - otherwise, the weight would pass through the lifter or vice versa). The feet of the lift also experience a reaction force, which, combined with the shoulder-reaction force, is equal to the action force (Newton's Third Law). The feet also experience friction on the floor surface in opposite directions (which cancel out, so the lifter is stationary on the ground) :)
What else can I help you with?
Are the forces acting on the weight lifter and the weights balanced or unbalanced?
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.
If the weight holders of the experiment have the same weight may their weight's be neglected?
Yes, if the weight holders in the experiment have the same weight, their individual weights can be neglected because they would exert equal forces in opposite directions, effectively cancelling each other out. This allows for a more simplified analysis of the forces acting on the system.
Force table question If the weights of the weight hangers were exactly the same could their weights have been neglected in the computations Explain?
Yes, if the weight of the hangers were exactly the same, their contribution to the forces acting on the system could be neglected in the computations. This is because the equal weights would create equal and opposite forces, leading to a balanced system where their effects cancel each other out.
How does the of a 115kg barbell compare to the weight of the lifter?
The weight of a 115kg barbell is constant. The lifter's weight, however, will vary. If the lifter weighs less than 115kg, the barbell will be heavier relative to their weight. If the lifter weighs more than 115kg, the barbell will be lighter relative to their weight.
What is the force acting on a weight and what are the forces acting on weightlifter?
The force acting on a weight is its gravitational force, which is the force pulling it downward towards the Earth. The forces acting on a weightlifter when lifting a weight include the gravitational force acting on the weight being lifted, the normal force exerted by the ground pushing back up on the weightlifter, and the muscular force applied by the weightlifter to lift the weight against gravity.
Are the forces acting on the weight lifter and the weights balanced or unbalanced?
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.

What is the difference between a ballet dancer and a weight lifter?
a weight lifter has to have a surtain amount of fat to lift the weights and a ballet dancer has to be skinny and flexible
Weight lifter strains to lift a record amount without moving the weights from the floor A sportscaster lifts her microphone to report on the attempt Who is doing more work?
the Olympic Weight lifter because the weights are much heavier then the microphone

What are the forces will be acting on the aircraft?
lift,thrust,weight,drag,
When you drop the apple what are the forces acting on it?
There is the apple's weight (mass * gravity) but there is also the air resistance acting against the object's weight.
Are all forces 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.
What is the force acting on a weight and what are the forces acting on weightlifter?
The force acting on a weight is its gravitational force, which is the force pulling it downward towards the Earth. The forces acting on a weightlifter when lifting a weight include the gravitational force acting on the weight being lifted, the normal force exerted by the ground pushing back up on the weightlifter, and the muscular force applied by the weightlifter to lift the weight against gravity.
How many weights come with this system?
This is a rather deluxe set intended for the serious lifter. You will get 20 pair of dumbbells, ranging in weight from 55-100 lbs.
