What is viscous force directly proportional to?
Viscous force is directly proportional to the velocity gradient, which represents the change in velocity per unit distance. This means that the higher the velocity gradient, the greater the viscous force acting on the fluid.
Are force and mass directly proportional or inversely proportional?
Force is directly proportional to mass provided the acceleration is constant.
Is viscous force present in air?
yes, viscous force is present in air. it is proportional to the velocity and area of the body and acts in the opposite direction of velocity.
Why is it harder to move through a vicous liquid?
Moving through a viscous liquid is harder because the liquid has higher resistance to flow due to its thickness and stickiness. This resistance causes a drag force that opposes the movement of objects through the liquid, requiring more force or energy to overcome.
What is Gravitational Force directly proportional to?
Gravitational force is directly proportional to the product of the masses of two objects and inversely proportional to the square of the distance between them.
How does the earths radius affect the gravitational force on a object at its surface?
The Earth and the object exert a gravitational force on each other, but only the Earth's is big enough to measure. So, the formula for gravitational force include the distance from one body's surface to its center and the same for the other body. The length of the radius is directly proportional to the body's gravitational force.
How can the pressure acting on the surface be increased by the force acting on the surface?
Simply pressure is the force per unit area. So Pressure is directly proportional to the force applied. Hence by increasing the force we can increase the pressure.
Is work directly or inversely proportional to force?
Work is directly proportional to force; the amount of work done on an object is directly related to the force applied to it. More force results in more work being done.
How does surface area and force affect pressure?
Pressure is force per area, so P = F/A where pressure is P, force is F and A is area. So Pressure is directly proportional to the force exerted on a surface. So increasing a force by a factor of 2, say, increases the pressure on the surface by 2 also.
Is accelaration directly proportional or inversely proportional to the force?
Directly. That's why you can't move a car by blowing on it.
Why is gravity strongest at Earth's surface?
Gravity is strongest at the earths surface because it's atmosphere is v dense and so the force inc.this happens because force is directly proportional to density.
When acceleration is held constant and objects of different mass are observed are mass and force directly proportional or inversely proportional?
directly proportional because force=(mass)(acceleration) (f=ma)
