How does force of friction depend upon the angle of the incline
On which of the following quantities does the kinetic friction force associated with a solid surface depend on? Note there might be more than one correct choice. The kinetic friction force depends on the two materials that touch each other. on the weight of the object. on the normal force by the supporting surface on the size of the surface area where the two objects touch.
What can you say about the value of the static friction force between two surfaces if the contact area is changed?
The coefficient of kinetic friction between two materials depends on Select one: a. the normal force b. the surface area in contact c. the relative speed of the surfaces d. the type of surfaces
The drag force on a cannonball falling through the air does not depend upon what factor? Group of answer choices the density of air the cannonball's cross-sectional area the cannonball's mass the cannonball's drag coefficient with air the cannonball's speed
2) [10 marks How does the speed of deep water waves depend upon their wavelength (you may neglect surface tension and the depth of the water)? How does the period of oscillation of a drop of water depend upon its radius (you may neglect gravity and any interaction of the drop with its surroundings)? Estimate the length-scale at which the transition from gravity to surface tension being the dominant process to consider occurs. [The surface tension of water is approximately...
Upon what does the determination of a blood alcohol content (BAC) depend?
Question 1 What type of friction occurs when a body is already sliding in motion? Which direction is this friction force pointing? What does this say about the net force on the object now?
The magnitude of Flim between contacting surfaces is frequently of great importance in athletic activities. Excluding footwear changes and playing surface characteristics, , provide two examples in which an athlete attempts to manipulate friction (either increase or decrease) to his or her advantage and describe what the athlete does to affect friction (i.e., provide an indication whether change in the coefficient of friction or the normal reaction force is primarily responsible for the observed change).
a 55-Kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30. A horizontal 42 N force is applied to the box. what is the static friction force on the box? (I know that the answer is 42 N because my teacher told me but I need the 4 questions below answered regarding this question) 1) what is the minimum static friction force? 2) how do you calculate the maximum friction...
