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.
If the velocity of a moving body is doubled what does this do to kinetic energy and the momentun of the body?
Doubling the velocity of a moving body quadruples its kinetic energy while doubling its momentum. This relationship highlights how kinetic energy is proportional to the square of the velocity and momentum is directly proportional to velocity.
Newton's first law is a special case of the second law Explain?
Newton's first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. This can be seen as a special case of the second law because if the net force acting on an object is zero (as in the case of no external force), the acceleration will be zero, and the object will either remain at rest or continue to move at a constant velocity, in accordance with the first law.
How do you describe newton's 2nd law?
Newton's second law states the rate of change of momentum of a body is directly proportional to the resultant force on the body and is in the same direction as the resultant force.
What is a forcewhat are the various effects of force on an object?
Force is an influence tending to change the motion of a body or produce motion or stress in a stationary body. Effect of force: 1.Force change the motion of a body:- force change the motion of body that are already in motion and produce motion in a stationary body. Example a car moving on a road suddenly hit behind by a truck, you will notice the tendency of the car motion increase. the force applied by the truck affect the motion of the car. A stationary body hit behind by a moving body, the position of the stationary body changes. 2.Force change the direction of both stationary body and body in motion:- Newton's second law state that the rate of change of momentum of a body is directly proportional to the applied force and take place in the direction in which the force acts. 3.Frictional force:- is a force that oppose the motion of one body over the other. Effect of frictional force: a.It leads to wasting of energy, when two surrounding forces move over each other, heat is generated as a result of friction. the energy required to turn the machine, will be converted heat energy which reduces the energy output. b.It leads to wearing away of the surfaces in contact. 4.Gravitational force field:- Gravitational force field causes a body thrown up to fall back on the ground.
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How we can relate the force with the change of momentum of a body?
The force acting on a body is directly proportional to the rate of change of its momentum, as given by Newton's second law of motion (F = dp/dt). When a force is applied to a body, it results in an acceleration, causing a change in the body's momentum. The greater the force applied over a period of time, the larger the change in momentum of the body.
How can you relate the force with the change of momentum of a body?
Newton's Second Law was originally formulated as: F=dm/dt. That is, the force is proportional (or equal, if the correct units are used) to the rate of change of momentum. The more force, the faster will the momentum change.
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How force is related to momentum of the body?
Force is directly related to the change in momentum of a body, as described by Newton's second law of motion. The force acting on an object causes a change in its momentum by accelerating or decelerating it. The greater the force applied, the greater the change in momentum experienced by the body.
The impulse experienced by a body is equal to change in its?
The impulse experienced by a body is equal to the change in its momentum. This means that when an external force is applied to an object, its momentum changes, causing the object to experience an impulse in the direction of the force applied.
How do forces cause a change in an object's momentum?
Forces cause a change in an object's momentum by exerting a push or a pull on the object. When a force is applied to an object, it accelerates in the direction of the force, resulting in a change in its velocity. This change in velocity over time results in a change in momentum, according to the equation: force = change in momentum / time.
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.
What is an impulse in scientific terms?
Impulse is force x time where the assumption is that the force is high and the time is short. Since force is rate of change of momentum of a free body, then impulse amounts to a sudden change of its momentum.
Initial momentum of a body is 200kgms and it changes to 500kgms in seconds on application of force find the change in momentum and rate of momentum and force applied?
Darn ! I was reading this and really getting into it and planning to tackle it. But you left out how many seconds ??? The change in the body's momentum is +300 kg-m/s . Tell us how many seconds, and we'll answer your other questions too.
What happens to the momentum of a body acted on by an external force?
If the force opposes the motion, it will reduce the velocity and the momentum of the body will decrease. If the force is in the direction of the motion, the velocity will increase and the momentum will increase.
What is an air bag in car how it saves driver from injury?
Impulse gives the impact on the body. Impulse is measured by the change in momentum. And rate of change of momentum is force which causes harm on the body. So as we extend the time duration for any change in momentum force is terribly reduced and hence no severe impact. Hence safe journey with a air bag behind the driver.
