a 500 g ball and a 200 g ball are dropped from a tower. both balls are the same size and there is no air resistance (friction). when do the balls hit the ground?\nboth balls hit the ground at the same time\nthe 200 g ball hits the ground first\nthe 500 g ball hits the ground first\nquestion 12\n1 pts\nhow does mass differ from weight?\nmass and weight are the same thing\nmass is the amount of matter in an object, while weight is the pull of gravity on that mass\nmass changes depending on location, but weight does not\nweight is the amount of matter in an object, while mass is the pull of gravity on that matter
Answer
Brief Explanations:
- For the first question, in the absence of air - resistance, all objects in free - fall near the Earth's surface accelerate at the same rate ($g\approx9.8m/s^{2}$), regardless of their mass. So both balls hit the ground at the same time.
- For the second question, mass is a measure of the amount of matter in an object, and it is an intrinsic property. Weight is the force exerted on an object due to gravity, calculated as $W = mg$ where $m$ is mass and $g$ is the acceleration due to gravity.
Answer:
- Question 11: Both balls hit the ground at the same time
- Question 12: Mass is the amount of matter in an object, while weight is the pull of gravity on that mass
