Which force needs to touch something to have an effect?
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
How does angle effect force of friction?
The force of friction between two surfaces increases as the angle between the surfaces increases, up to a certain point. This is because the component of the force perpendicular to the surfaces (normal force) increases as the angle increases, which in turn increases the maximum force of static friction that can be applied. Beyond a certain angle, the force of friction decreases due to the decreasing normal force.
What is the effect of decreasing the block in contact with the table on kinetic friction?
Decreasing the block in contact with the table reduces the normal force acting on the block, which in turn decreases the frictional force. This results in a lower kinetic friction force between the block and the table.
How does the force pushing 2 surfaces together effect friction?
The force pushing two surfaces together increases the friction between them. The greater the force pressing the surfaces together, the greater the frictional force that resists relative motion between them.
In the absence of friction the combined effect of the Coriolis force and the pressure gradient force produces what?
In the absence of friction, the combined effect of the Coriolis force and the pressure gradient force produces geostrophic balance. This balance results in a steady state where the Coriolis force is exactly balanced by the pressure gradient force, allowing for straight and parallel flow without any acceleration.

Effect of speed on the force of friction?
Friction is independent of speed once an object is moving since faster does not mean more friction.
Why does the input have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
What can effect the amount of frictions between two objects?
The two factors are the coeffiecient of friction, and the 'normal' force, which is equal and opposite to the weight of the object. The coefficient of friction is diffeerent for different objects. Friction force = Coeff. X Normal Force
How does angle effect force of friction?

How does friction affect the law of inertia?
Friction has no effect whatsoever on the law. But if friction is present, then the law can't be demonstrated, because the moving object always has an external force acting on it.
What effect does friction have on the motion of an object when it is the only force acting on it?
Friction slows down the motion of an object when it is the only force acting on it. It opposes the object's movement, causing it to eventually come to a stop.
Does friction effect braking force?
Yes, friction is essential for braking as it helps to slow down a moving vehicle by creating a resistance force between the brake pads and the wheels. The greater the friction between the brake components, the more effective the braking force will be.
What does the friction force vs normal force graph reveal about the relationship between friction force and normal force?
The friction force vs normal force graph shows that there is a direct relationship between the friction force and the normal force. As the normal force increases, the friction force also increases. This indicates that the friction force is proportional to the normal force.
