A. the ping-pong ball has less velocity B. the ping-pong ball has significantly more velocity C the ping-pong ball has the same velocity as the bowling ball D. not enough information peovided 4 If two objects with the same mass are moving at different speeds, the faster object has A more kinetic energy B. less kinetic energy. C. the same kinetic energy. D. double the kinetie energy 5. Slides A, B, C, and D are shown below. Which of these ramps would produce the fastest object at the botom of ths lide? 6. What is a scientifie claim A. statement about only the trends in data B. a statement about some process or relatsionship in the natural world backed by evidence С.the same as a hypothesis. D. a declaration of evidence

Answer 1

1) Yes, the object is motion will have kinetic energy

2) As the ball rolls up the ramp, it will gain gravitational potential energy because it is gaining height.

3) Ping pong balls are usually small than bowling ball. Therefore, to have same kinetic energy, ping pong ball will have significantly more velocity.

4) for same mass, the faster object will have more kinetic energy.

5) assuming that all slides are frictionless, slide A will would produce the fastest object as velocity is given by

v = sqrt (2gh) therefore, more height will give more velocity
