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.

What are the forces acting ona weightlifter and weights?
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.
A 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell How large is the NET vertical force acting on the barbell?
If a 90 kg weightlifter exerts a 1000 N force upwards against a 50 kg barbell, the NET vertical force acting on the barbell is 1000 N. It does not matter how heavy the weightlifter or the barbell might be.
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 are the forces on a plane when it is still?
When a plane is still on the ground, the main forces acting on it are weight and normal force. Weight is the force due to gravity acting downward, while the normal force is the force exerted by the ground perpendicular to the plane to support its weight. Additionally, there may be frictional forces acting on the wheels to prevent the plane from moving.
Why is the weight of the ruler not included as a force acting on the system?
The weight of the ruler is not included as a force acting on the system because it is an internal force within the system. Internal forces do not affect the overall motion of the system and therefore do not need to be considered when analyzing external forces acting on the system.

What force or forces are acting on the crate?
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
A weightlifter lifting a heavy weight uses?
Uses force

What are the forces on a airplane when it is still?
When an airplane is still on the ground, the main forces acting on it are the gravitational force acting downwards and the normal force exerted by the ground acting upwards to support the weight of the airplane. There are typically no aerodynamic forces acting on the airplane until it starts moving.
A crate is at rest on the ground what force or forces are acting on the crate?
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
What are the forces acting on the weight lifter and the weight?
(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) :)
Forces acting on a car when it is still?
When a car is still, the main forces acting on it are the gravitational force pulling it downwards and the normal force from the ground pushing it upwards. These two forces are equal in magnitude and opposite in direction, resulting in a net force of zero.
Are there forces acting on objects at rest?
Yes there is air force, Gravity, his weight etc.
