The word normal has several meanings. All the population under the normal curve is normal.
Normal is used in geometry and physics to mean perpendicular to.
Your weight depends upon your mass, and upon the force acting on it.
W = M x F. The force of gravity is attractive.

Does magnitude of normal force always equal the weight of the object?
No, not always directly opposite. The normal force is always perpendicular to the surface. So for a flat ground it will be directly opposite gravity or Weight.If you had an object on a ramp the normal force would be a diagonal line that is perpendicular with the ramp.
What is the effect of water on object submerged in water?
It is named as buoyant force which always acts in the upward direction ie opposite to the weight of the body. So actual weight appears to be reduced. Hence apparent weight loss
What are the forces on a hockey puck as it slides away on ice?
Friction in the opposite direction to the direction of motion. Weight directly downwards. Reaction force directly upwards.
What are three factors at work when an object is placed in a fluid.?
1. Weight of the object acting always downward which is due to gravitational pull 2. Buoyant force which acts always upward which equals to the weight of the displaced fluid. 3. As the objects starts moving within fluid then viscous dragging force comes into the scene and acts always opposite the direction of motion.
A scalar quantity has what?
A size but no direction. Mass is a scalar but the force we call weight is a vector: it always points down.
The normal force is always opposite in direction to weight?
Yes, the only time this isn't true is in circular motion.
What is the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
Where does sudden acceleration transfer the weight?
In the opposite direction to the course of acceleration.
What are forces equal in strength but opposite in direction?
It happens when 1 force is having larger magnituge and the other is less in magnitude ........ and then the forces does not balance each other Take the example of weight and tension of a body connected by string . weight and tension are always opposite in the direction if the weight is suppose 12 newton and tension is 10 newton , then same thing will happen , they can't balance each other ...... as the strength of weight is more than tension

How does affect an object?
weight is the force gravity exerts on an object. Therefore, it means that the greater weight an object has, the greater force is needed to move it in the opposite direction.
Anorexics have what percent body weight of normal weight?
It varies per individual. Almost always anorexics will have a noticeably less percent of body fat or weight from body fat that a "normal" or "average" weight person.
How does motion in a vertical circle differ from that in a horizontal circle?
During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.During motion in a vertical circle, the force of gravity (weight of the object) is in the same direction as the motion for half the time and in the opposite direction for the rest.For a body moving in a horizontal circle, gravity is acting orthogonally to the motion at all times.
Why is there a difference between the weight of an object in the air and it's weight in water?
Because of buoyancy ; something that acts in the opposite direction to the force of gravity to make the object feel lighter.
