Does friction cause more energy to be wasted if the object is heavier Why?
Friction between two objects = C X N. where C is the coeffiecient of friction for the objects in question, and N is the 'Normal' force. The normal force is the force equal and opposite to the object's weight. Therefore, if you increase the object's weight, the friction force increases, and the amount of energy wasted increases.
What is the downward pull of a object due to gravity?
The strength of the force in each direction between the earth and any mass is called the "weight" of the mass. The force is equal in both directions, which means that the weight of the mass on earth is the same as the earth's weight on the mass. The force acts along the line between the center of the earth and the center of the mass. The direction toward the center of the earth is customarily referred to as the 'down' direction, and toward the center of the mass as the 'up' direction.
What force is acting when you are sitting on a chair?
Your weight pushing down on the chair is the action force. The reaction force is the force exerted by the chair that pushes up on your body
Does an object with momentum always have energy?
Not if it's potential energy. Only objects with kinetic energy have momentum.
What scientific rule states that the buoyant force an an object is equal to the weight of the fluid displaced by the object?
Since the object is submerged, we know that the buoyant force is not sufficient to overcome the weight of the object, otherwise it would be floating rather than being submerged. Therefore, the buoyant force is equal to the weight of the displaced water, not the weight of the object itself.
Is the normal force is always opposite in direction to weight?
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.
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
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.
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.
