Why is it harder to move through a vicous liquid?
the viscous force is directly proportional to the viscosity of the fluid. so the more viscous a liquid is, more the viscous force and harder it is to move for a bod through it.
What is viscous force directly proportional to?
velocity gradientthe velocity with which water flow.this is due to the property of viscousity
Are force and mass directly proportional or inversely proportional?
Force is directly proportional to mass provided the acceleration is constant.
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 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 does weight affect frictional force?
Given an object if contact with a surface, the limiting frictional force is directly proportional to the normal reaction to the weight of the object at its point of contact with the surface.
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.
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.
Is accelaration directly proportional or inversely proportional to the force?
Directly. That's why you can't move a car by blowing on it.
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)
How force affects mass and acceleration?
force is directly proportional to acceleration and acceleration is inversely proportional to mass of the body
What is the name of the frictional force between the surface and the air?
Viscous drag
