How can the forces in agame of tug-of-war result in equilibrium?
Both sides are pulling the opposite dirrention so acceleration is zero which is equilibrium
How can there be force without acceleration?
To get an acceleration, there has to be a net force - and conversely, if there is a net force, there is acceleration. In many common situations, there are two or more forces that cancel one another - the vector sum of the forces is zero, and therefore there is (by definition) no net force, and no acceleration. Here is one example. A book lies on the table. Gravity pulls the book down, but the book doesn't accelerate downward. What is the counter-force? It has to be the table pushing the book up. (Of course, by Newton's Third Law, if the book pushes down against the table, then the table pushes up against the book.)
Can there be force without movement?
there can be force without movement. an example of this would be when a person pushes against a wall :)
Do helicopters defy gravity?
The rotor blades are designed so that as they spin they push down on the air, which in turn pushes up on the blades, creating lift that acts counter to gravity.
Why does a person move forward when he or she pushes on the sidewalk?
The person's feet push backward on the sidewalk; the sidewalk pushes forward on the person.
How does friction decrease the acceleration of a car?
friction decreases the acceleration of a car by creating a greater force which pushes against the acceleration force. the friction is a force, but more of it means that whatever is pushing against it ( acceleration in this case) is made smaller.

What is the name of the force that pushes agisnt an aireplane as it tries to move forward through the aire?
'Thrust' pushes against it from the rear, and 'drag' pushes against it from the front.
If the child pushes you who will have the larger acceleration you or a child?
well it does depend on how much you weigh if you are a child then you both would have the same acceleration but if you are an adult then the child would have no acceleration. O: i am so smart.

The blades of a fan keep on moving for sometime even after the fan is switched off?
It is most likely the momentum that carries the blades spinning, when you switch the fan off the energy doesn't completely disappear , it exists and still pushes the blades round.
How wave generated in sea?
The waves usually get their energy from the wind. The wind pushes against any small irregularity in the water, creating small ripples, pushes against the small ripples producing larger waves, etc.The waves usually get their energy from the wind.

What is the action and reaction forces when touching you finger to your nose?
There are two forces involved; the finger pushes against the nose, and the nose pushes against the finger.
