Which direction does friction work?
Friction's direction is always against the direction work is being applied to.
What work is being done when pulling?
It is the pulling force applied multiplied by the displacement of the object being pulled in the direction of the pulling force.
What is importance of air resistance?
Air resistance is the force exerted on an object when it travels through an atmosphere. It can be used to slow objects down, such as skydivers, however in most applications, the object is to avoid air resistance. Vehicles, such as a Toyota Prius, or air planes, such as a commercial jet, strive to avoid air resistance (or become more aerodynamic) as a way to decrease fuel consumption or increase maximum speed. Air resistance increases exponentially with an object's velocity.
What effect will the direction of the applied force to a book have on the amount of work being done?
The work being done will be increased if you pick it up instead of dragging it due to the friction.
What affects the acceleration of an object?
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
Which direction does friction work?
Friction's direction is always against the direction work is being applied to.
Which direction does friction always work?
Friction's direction is always against the direction work is being applied to.
What work is being done when pulling?
It is the pulling force applied multiplied by the displacement of the object being pulled in the direction of the pulling force.
What is the cause of TONE in any musical Instrument?
Vibrations or wind resistance. Each key/position on an instrument then changes the dynamics and resistance of pressure being applied via wind. Drums are another story

Why does my 115v motor start in different directions each time it's energized?
It's due to the cheap design of the motor. When the motor stops, there is some torque being applied to it against the direction that it was moving. The more torque being applied, the more energy is required to get it rotating. So since there is torque in one direction, it will require less energy to get going in the opposite direction of that last time it was running, therefore to save money, it's better to have it turn the opposite direction. A better, more expensive motor will be able to easily supply enough energy to overcome the torque being applied after it stops, so it can always move in one direction.

What is an arrow showing the direction of force?
Force arrows were developed by Isaac Newton and is a universal representation of force. The force arrow represents the direction a force was being applied to and the length of the arrow represented the amount of force being applied. Hope this helps... If not... TOO BAD! JKJKJK
Why are the readings on a ammeter always different?
The readings on an ammeter indicate the current being drawn by a load in a circuit. This load is basically a resistance to current flow. The higher the resistance, the lower the current. The supply voltage has a direct effect on current flow. The higher the voltage applied, the higher the current will be. So the readings will vary on the ammeter according to fluctuations in load and or resistance of the circuit and the applied voltage.
What affects the acceleration of an object?
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
When a force is applied that moves an object in the direction of the applied force is gravity done?
Gravity is indeed a force, but only one out of many. magnetic, frictional, mechanical ... . When an ordinary force applied to an object, (me pushing my wheelbarrow) this would not be considered as being affected by gravity.
How it is friction related with work?
Work = Force x Distance Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.
