Does a force exerted on an object always increase the object's speed? If yes, explain why. If no, provide an example in which an external force does not increase an object's speed.
yes.According Newton second law of motion the net force acting on the object is equal to change in its momentum
As long as there is a non-zero net force acting on the object, it will have a non-zero acceleration and therefore it will continously change its velocity.
Does a force exerted on an object always increase the object's speed? If yes, explain why....
Is it possible to have a non-zero net force on an object that does no work on the object? if not, explain why. if so, provide an example.
Which combination of options is most accurate (A) Acceleration always means an object's speed is increasing or decreasing. (B) When the net force is perpendicular to momentum, the object will turn. (C) A projectile's time in the air is fully determined by its initial horizontal velocity. (D) Change in momentum is directed in the same direction as the net force. (E) None of the above Force and Energy Which combination of options is most accurate. (A) Equilibrium corresponds to when...
An object is moving at a constant speed around a circle. In which of these cases does the magnitude of the centripetal acceleration of the object increase the most? The radius of the circle doubles The object's speed doubles The object's speed is halved The radius of the circle is halved
Conceptual Question: Use Newton's First Law to explain why there must be a force constantly acting on any object in circular motion, even if it is staying at constant speed. Use Newton's Second Law to write an equation for the centripetal force in terms of the speed and radius of the object's motion as well as to determine the direction in which the force points Newton's Third Law is true in all stuations, including circular motion. Explain why the equal...
Does a stock split provide an increase in wealth for a shareholder? If yes, how? if no, why not ?
DJ Balance 6. An object of known mass M with speed vo travels toward a wall. The object collidés with it and bounces away from the wall in the opposite direction in which the object was initially traveling. The wall exerts an average force Fo on the object during the collision. A student must use the equation Ap = FAt to determine the change in momentum of the object from immediately before the collision to immediately after the collision. Which...
Does a force applied to an object always produce motion? What can you figure out about the forces on an object just by observing its motion? If no forces are acting on a body, can the body be in motion? Explain.
(a) Can the kinetic energy of an object be negative? If no, explain, if yes, give an example. (b) Can the potential energy of an object be negative? If no, explain, if yes, give an example.
