What forces act on you as you walk across a room? Draw a free-body diagram showing all of them. Which force or forces propel you forward? Why is it more difficult to walk on a slippery surface than on a nonslippery one? Explain how you use Newtons third law to control your motion.
Why can we neglect forces such as those holding a body together when we apply Newton’s second law?
What if we have air resistance in the environment? Will there be any differences? Justify your answer by using Newton’s 2nd Law.
An astronaut is doing a repair work on a space station. Suddenly, he loseshis grip and finds himself drifting away from the space station. In less than an hour, because of oxygen depletion, he will simply be…DEAD! What canhe do so he can return safely to the space station? Explain using Newton's Laws of Motion.
You pull a sled with a constant force across a level field and it moves with constant velocity instead of an increasing velocity. Doesn’t this violate Newton’s first and second laws of motion, which imply that no force is required to maintain a constant velocity? Explain this seeming contradiction. Hint: is your pulling force the only force acting on the sled?
Suppose you jump from the cliffs of Acapulco and perform a perfectswan dive. As you fall, you exert an upward force on the Earth equalin magnitude to the downward force the Earth exerts on you. Why,then, does it seem that you are the one doing all the accelerating?Since the forces are the same, why aren’t the accelerations?
What is a net force? What is an unbalanced force?
If you are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle a sharp upward smack, forcing the bottle rapidly upward. Think about what subsequently happens to the ketchup, which is initially at rest, and use Newton’s first law to explain why this technique is so successful.
Suppose you jump from the cliffs of Acapulco and perform aperfect swan dive. As you fall, you exert an upward force on theEarth equal in magnitude to the downward force the Earth exerts on you. Why, then, does it seem that you are the one doingall the accelerating? Since the forces are the same, why aren’tthe accelerations? Draw and Explain.
How does acceleration vary with the force? How does acceleration vary with the mass? And is the weight of the body the same as its mass? Explain
How do I find weight without mass or drag given. How do I answer the last question?
