Explain why your weight would be less in the moon than on earth even though your mass would not change. Use the law of universal gravitation in your explanation.
A bolt falls off an airplane high above the ground. How far does the bolt have to fall before its speed reaches 100m/s (about 200 miles per hour)? You should ignore air friction in your calculation.
A car is traveling south at a speed of 69 miles per hour and then begins traveling west but continues traveling at the same speed. Which of the following has changed? A. velocity B. gravity C. mass D. speed
a 0.4 kg block rests on a desk. the coefficient of static friction is 0.2. You push the side of the block but do not have a spring scale to measure the force you use. the block does not move. which statement is true about the force of static friction?
When is an object that has been dropped from a great height through the air closest to vein in a free fall? At it's terminal velocity <-- this one? When it has it's smallest acceleration When it's velocity downward is largest When the velocity downward is smallest
