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.
How does the normal force on you compare to your weight when you stand on a floor?
When you stand on a floor, the normal force acting on you is equal in magnitude but opposite in direction to your weight.
What direction does weight always act in?
Weight always acts in the downward direction due to gravity.
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.
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.
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
Why is weight and normal force action-reaction pairs?
Weight and normal force are action-reaction pairs because weight is the gravitational force pulling an object downward towards the center of the Earth, while the normal force is the force exerted by a surface perpendicular to the object to support its weight. These two forces are equal in magnitude and opposite in direction, according to Newton's third law of motion, ensuring that the object stays in equilibrium.
When a block is lying on soomthy surafce its weight is balanced by?
When a block is lying on a smooth surface, its weight is balanced by the normal force exerted by the surface in the upward direction. The normal force is equal in magnitude and opposite in direction to the force of gravity acting on the block. This balance of forces keeps the block stationary.
What is force exerted perpendicular to the surface of the object called?
The force exerted perpendicular to the surface of an object is called the normal force. It acts in the opposite direction to the force applied on the object and helps to support the weight of the object.
What is the force that acts in the opposite direction of lift?
The force that acts in the opposite direction of lift is weight, which is the force exerted by gravity pulling the object downward. It acts vertically downward from the center of mass of the object.
What The buoyant force on an object is equal to the weight of the water it What?
The buoyant force on an object is equal to the weight of the water it displaces. This principle, known as Archimedes' principle, explains why objects float or sink in fluids. The buoyant force always acts in the opposite direction to gravity.
