Cart X Cart Y A student must conduct an experiment to verify the conservation of momentum for a closed two-cart system. Cart X and cart Y travel toward each other and eventually collide, as shown in the figure. The student has determined the following procedure. Step 1: Measure the mass of cart X and cart Y with a balance. Step 2: Use a motion sensor to record data of the velocity of each cart before, during, and after the collision. Step 3: Use the data and Epo = Ep; to determine if the right-hand side of the equation is equal to the left-hand side of the equation. Which of the following steps should the student add to the procedure so that the conservation of momentum can be experimentally verified? CHOOSE ONE ANSWER A Conduct the experiment on a smooth, level surface. B Attach adhesive strips to each cart so that they stick together after they collide. C Ensure that the mass of each cart is the same. D Ensure that the initial speed of each cart is the same.

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
