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...
Another frequent instance of constant acceleration is abody decelerating in the presence of friction.Friction is directly proportional to the weight of an object, and so it will remain constant over time. Remember from our gravity example that a constant force implies a constant acceleration. Frictio...
G-force, also known as gravitational force, is a term used to describe the force of gravity acting on an object. It is a measurement of the acceleration experienced by an object due to gravity and is typically measured in units of acceleration. G-force is an important concept in physics,...
Acceleration due to gravity causes a falling object to pick up speed as it travels. Because a falling object's speed is constantly changing, you may not be able to measure it accurately. However, you can calculate the speed based on the height of the drop; the principle of conservation of...
How is g-force calculated? G-force is calculated by dividing the acceleration due to gravity (9.8 m/s^2) by the acceleration of the object. Can humans survive high g-forces? Yes, humans can withstand up to 9 g's for a short period of time with proper training and equipment. However...
The space shuttle had a takeoff acceleration approximately 3.5 times the acceleration due to gravity. What was the speed of the space shuttle 120 s after takeoff if it maintained that acceleration? Just after hitting the runway, a plane has ...
Under gravity, the acceleration of the body remains constant. So this is a uniformly accelerated motion. {eq}a = - g = - 9.8 \frac{m}{s^2} \text{...Become a member and unlock all Study Answers Start today. Try it now Create an a...
The object is also subjected to gravity and drag. Drag is generated when a solid object moves through a fluid medium such as water or air. Drag increases with velocity -- the faster the object travels, the more drag it experiences. We measure an object's motion using the factors described...
If that's the case, then a modification of gravity, not some unseen particle, could explain the effects attributed to dark matter. In the 1980s, physicist Mordehai Milgrom suggested that Newton's second law of motion (force = mass x acceleration, f = ma) should be reexamined in the ...
How people wake up and regain alertness in the hours after sleep is related to how they are sleeping, eating, and exercising. Here, in a prospective longitudinal study of 833 twins and genetically unrelated adults, we demonstrate that how effectively an individual awakens in the hours following ...
