Unbalanced forces acting on an object produce motion?
The second law of Newton says that the sum of all the forces acting on an object is equal to the acceleration of this object, in a given frame of reference. If the sum of forces isn't equal to zero, therefore the acceleration isn't to. So the object has a speed and is in motion, in the frame of reference chosen.
What is the magnitude of force acting on a body moving with constant velocity?
Certainly not. An object has momentum on account of its motion, which depends on its mass and its velocity. Force may be involved in the object's motion, but doesn't need to be. If we let the discussion become somewhat flabby, we can imagine a constant force applied to an object, and asked what happens to the object's momentum. An object with a constant force acting on it exhibits constant acceleration in the direction of the force. In that situation, the object's speed, and therefore its momentum, are proportional to the time the force continues to act on it.
What is the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
What are equal forces acting on an object in opposite directions?
Equal forces acting on an object in opposite directions are called balanced forces. If they are on the same line of action, they are called couple forces.
Balancing the forces acting on an object give you the net force?
If the forces acting on an object are perfectly balanced, the resulting net force is equal to zero.
What is a direction of impulse?
impulse is equal to force which is acting on the body and ti me in small interval which is equal to momentum.so impulse is equal to change in momentum and direction of impulse is consider the direction of force and change in momentum.
Is it false that balance forces are equal forces acting on an object in opposite directions?
Is the greatest velocity a falling object reaches is called its momentum
What does the impulse-momentum theorem state?
Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).
The momentum of a falling leaf is and the momentum of a falling pincone is what?
momentum is equal to the mass of an object x velocity of an object
Object A strikes object B the momentum of object B increase what happens to the momentum of object A?
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
Any time there is no change in the movement of an object what is true of the force pairs acting on the object?
They are equal in magnitude.
Is it true that momentum is not equal to the mass of an object divided by its velocity?
That is true because momentum is mass times velocity
Is it possible for an object to have serveral forces acting on it and still not change its motion?
Yes. As long as the forces are equal and opposite the object will not change its motion.
What conversation states that the momentum of an object before the collision is equal to the momentum of the object after the collision?
That law is called, precisely, the Law of Conservation of Momentum.
How could you describe a situation where an object velocity does not change?
if velocity is constant, that means then the net acceleration acting on the object is equal to zero
Unbalanced forces acting on an object produce motion?
The second law of Newton says that the sum of all the forces acting on an object is equal to the acceleration of this object, in a given frame of reference. If the sum of forces isn't equal to zero, therefore the acceleration isn't to. So the object has a speed and is in motion, in the frame of reference chosen.
Why is the earths acceleration not equal to and opposite the objects acceleration?
There is no reason it should be the same.Acceleration is the rate of change in velocity.To change acceleration a force is required and the change of acceleration depends on the force applied and the mass of the object on which the force is acting.
