6. How much would you weigh on Jupiter, where acceleration due to gravity is 2.65g? g is the acceleration due to gravity on Earth. Assume your mass is 42 kg. 相关知识点: 试题来源: 解析 g=9.8 .FromF=ma,wefindthatapersonwithmass42kgwouldweigh(9.8) (2.65) (42) =1091 N on Jupiter....
Acceleration Due to Gravity: When a very large object, such as a planet, exerts a gravitational force on an object that is much smaller than the planet, the planet's gravity will cause the object to fall downward at a certain rate. This rate is independent of the mass of the ...
Space farming studies the effects of microgravity on plant growth, focusing on how plants orient roots and stems with reduced gravity, which is crucial for potential farming on the moon or Mars. In space, efficient use of energy is vital, so researchers use light-emitting diodes (LEDs) to mi...
How fast would you have to drive around a circle of radius 30 feet (10 m) to experience an acceleration equal to the acceleration due to gravity? Centripetal Acceleration: To move in a circle, a force is needed with its dire...
Of course, you are not actually weightless, because the Earth's gravity is holding you and everything in the shuttle in orbit. You are actually in a state of free-fall, much like jumping from an airplane, except that you are moving so fast horizontally (5 miles per second or 8 kilomet...
You drop a rock off a bridge. How fast is it going after 2.0 s?Freefall:When you drop a rock off a bridge, the velocity of the rock increases at the rate of the gravitational acceleration g. To compute the velocity at any time t, we take the initial velocity as zero and use...
Constant accelerationis when thevelocity changes at a constant rate. Example: Imagine you toss a beanbag into the air. The bag rises into the air, coming to a halt at the top of its path. Then, it rapidly begins to descend until it falls into the palm of your hand. Other Gravity-rela...
Accelerometers are the stuff of rocket science—quite literally! Mounted in spacecraft, they're a handy way to measure not just changes in rocket speed but also apogee (when a craft is at its maximum distance from Earth or another mass, so its acceleration due to gravity is at a minimum)...
On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2. Since this is just a different scale for measuring acceleration, it not only applies to gravity, but can be used to quantify any acceleration. How g-force relates to harsh driving As mentioned, ...
This acceleration can change the shuttle's velocity by as much as 1,000 ft/s (305 m/s). To place into orbit or to de-orbit takes about 100-500 ft/s (31-153 m/s) change in velocity. Orbital adjustments take about 2 ft/s (0.61 m/s) change in velocity. The engines can start ...
