Pre-lab exercise The lab asks you to design and carry out measurements that will allow you to determine the momentum, K = 1.2mv^2 of gliders on an air-track before and after the gliders collide. Two gliders of equal mass approach each other from opposite ends of the air-track with the same speed. Which of the statements about this situation are true? T/F Momentum is a vector quantity. T/F The gliders have identical momenta, p. T/F The gliders have identical kinetic energy. T/F The total momentum of the system is zero. T/F The total kinetic energy of the system is zero. P = mv , and kinetic energy,Explanation / Answer
True Momentum is a vector quantity.
False The gliders have identical momenta, p.
the gliders have same magnitude of momenta but direction is oposite
True The gliders have identical kinetic energy.
as mass and velocity is same
True The total momentum of the system is zero.
False The total kinetic energy of the system is zero.
the kinectic energy is both gliders is positive
