The least massive of the two objects will have the greatest kinetic energy. their velocities are different), the momentum of each object will be … a. 1. Who was prime minister after Winston Churchill? False.A vector can have any combination of positive or negative x- or y- components. When that inertia is in motion, the object has momentum. Like all vector quantities, the momentum of an object is not fully described until the direction of the momentum is identified. (a)True, because magnitude is a pure number. • Answer: True. If two objects of the same mass are moving in opposite directions but at the same speed (i.e. b. What are their momentum? Now we are familiar with what are vectors and scalars. The combination of force and time is what is referred to as an impulse. True and false. Review Session Home - Topic Listing
The forward moving object will have the greatest momentum. When you start a browser program by default the first thing you see is? Object A has more momentum than object B. b. An object with mass will have momentum. e. FALSE - The direction of an object's momentum vector is in the direction that the object is moving. . Click hereto get an answer to your question ️ State whether given statement is True or False.A quantity which can be represented completely by magnitude only, is called a vector quantity. Momentum as a Vector: Momentum is a vector and has a direction. sujal6372 sujal6372 8 hours ago Science Secondary School 2). • Answer: True. I know momentum is a vector quantity but it gets tricky with angular momentum as it is does not just point in the x y plane. Card 5. FALSE - The Joule is the unit of work and energy. Name the physical quantity whose unit is kg.m/s. Impulse is a quantity which depends upon both force and time to change the momentum of an object. Explain the rules for the ray diagram for spherical lenses. c. FALSE - An object which is traveling east could encounter a collision from the side, from behind (by a faster-moving object) or from the front. FALSE - The Joule is the unit of work and energy. 22. Chapter 8 Momentum Class Date vector 20. 21. (c) False, total path length can also be more than the magnitude of displacement vector of a particle. True . Linear momentum is always in the direction of Velocity. False - the thing to remember is that momentum is conserved. Ask your question. This impulse acts upon the object to change its velocity and thus its momentum. This is the impulse-momentum change theorem. Back. How long will the footprints on the moon last? True or False; The standard unit on momentum is the Joule. The momentum lost by one object is equal to the momentum gained by the other TRUE FALSE 7. True d. Two objects of varying mass have the same momentum. 5. When vectors are multiplied by scalars, then, the result is anothervector. Since work is a scalar quantity, power is also a scalar quantity. True. T: Momentum is a vector quantity. Net force is the total external force applied on a body TRUE FALSE 6. False; its a VECTOR quantity. 1. Net force is the total external force applied on a body TRUE FALSE 6. 1. Most collisions tend to be partially to completely elastic. The units of momentum of kg-m/s. 2012-11-01 21:18:43 2012-11-01 21:18:43. Ch. Momentum is conserved in an elastic collision but not in an inelastic collision. That makes velocity a vector quantity. The kinetic energy of A is 45 J and the kinetic energy of B is 100 J. e. TRUE - When comparing the momentum of two objects to each other, one must consider both mass and velocity; both are of equal importance when determining the momentum value of an object. However, it could have some potential energy and thus have mechanical energy. Einstein stated the second law in terms of momentum TRUE FALSE 5. True,velocity is a vector quantity,it is specified by a magnitude and direction. FALSE - When comparing the size of two momentum vectors, the direction is insignificant. Which of the following statements are true about momentum? If an object does not have momentum, then it definitely does not have mechanical energy either. Only its acceleration would be westward. TRUE - A perfectly elastic collision is a collision in which the total kinetic energy of the system of colliding objects is conserved. the momentum of an object varies directly with the speed of an object. True or False; Momentum is a vector quantity. TRUE - There is significant bounce in the collision between a tennis racket and tennis ball. C. Distance is a scalar quantity but displacement is a vector quantity. Vector Quantities – Force, Electric field, Angular Momentum, Magnetic Moment, Linear Momentum, Average Velocity. Comments. Momentum is a vector quantity. Q6. 6 Momentum 14 Question 13 • True or False: When you apply an impulse to something, you change its momentum. True or false. State true or false. False. false. D. ... State the following statement is true of false: Each component of a vector is always scalar. Momentum before = Momentum after … g. TRUE - If large amounts of kinetic energy are conserved when a ball collides with the ground, then the post-collision velocity is high compared to the pre-collision velocity. Answer to: Explain and state the function is true or false. A ball is dropped from rest and collides with the ground. Answer: The total momentum of the bullet and the gun before firing is zero as the velocities of them is zero. Because p = m v. scalar and v is vector then p the momentum has to be a vector. true. Is there a way to search all eBay sites for different countries at once? In a collision, the net impulse experienced by an object is equal to its momentum change. . The law of conservation of momentum states that, in the absence of an external force, the true momentum of a system remains unchanged. a. Log in. (c) False, total path length can also be more than the magnitude of displacement vector of a particle. - 30568471 1. TRUE - In any collision between two objects, the colliding objects exert equal and opposite force upon each other. If the objects have different masses, then these equal forces will produce different accelerations. In each of these scenarios, the direction of the force would be different. This statement is true only if the particle is moving in a straight line. Which of the following statements are true about collisions? i. Angular momentum is a vector quantity that has a direction to it. In a collision, the two colliding objects could have different acceleration values. Add your answer and earn points. Momentum equals the mass times the velocity. A moving object collides with a stationary object; the stationary object has significantly less mass. :: Momentum is a vector quantity. Front.
