Question

When you drop a bowling ball & a tennis ball they hit the floor at the same time but when they hit the floor they have the same what? A. speed B. force C. momentum D. all of the above. I think it is D but I can't find anywhere what they have the same. Thanks

Answer 1

only the speed is the same

since momentum is speed times mass, the bowling ball will clearly have greater momentum.

Since force (weight) is mass times gravity's acceleration, the bowling ball clearly weighs more, so has greater force.
