What is a situation when you might travel at a high velocity but with a low acceleration?
"Acceleration" simply means how quickly velocity changes. Thus, such a situation could arise, for example, whenever you are riding in a car - most of the time the car won't be accelerating. If that isn't fast enough for you, in airplane travel the situation is similar. The Earth's movement around the Sun - at about 30 km/second - is even faster, and the velocity doesn't change quickly. In this case, it takes half a year, to change from 30 km/second in one direction, to moving at 30 km/second in the opposite direction. Since the orbit is almost circular, you can calculate the actual acceleration as speed squared / radius (where the radius is the distance from Earth to Sun in this case). The result of the calculation, in this case, is about 6 mm/second squared - a tiny fraction of Earth's gravitational field, for example.
What else can I help you with?
How gravity and air resistance are related to an object's terminal velocity?
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.
How do scientists generate hypotheses?
two ways I know of: contemplation, observation 1. if you see lights come on and go off when someone touches something on the wall, you might hypothesize a relation between the action and effect 2. lacking observation, some brilliant people apply all that they know about an issue and "jump" to a conclusion ie a hypothesis. One example might be by knowing the established relation F=ma (force = mass times acceleration). One might hypothesize that a similar relation might hold for energy (and it does, Einstein's E=mc^2 energy=mass times square of a velocity )
When lions prey on a herd of antelope some antelope are killed and some escape which part of Darwins concept of natural selection might be used to describe this situation?
Survival of the fittest would be used to describe this situation.
What is an example of terminal velocity?
An example would be "any object that is moving through the air, water or other substance at a rate such that it cannot possibly go faster without additional force being applied." "Terminal Velocity" in dropping a rock from an airplane might mean "the fastest the rock can possibly fall on its own." Once the rock reached that velocity, it would not be able to go faster despite that it had accelerated to that point without additional force (or increased gravity) being applied to the rock. rock from plane when force down = force up force down = mg (newtons) force up = force of air resistance (velocity ^2* drag coefficient ) newtons. you can use known terminal velocity to calculate drag coefficient if mass is known.
Why does it take more force to accelerate a more massive object?
A force will not increase or decrease an acceleration. If the force is constant, it will cause a constant acceleration. It may increase or decrease the speed. The change of velocity - for the same force - is the same, whether the speed is increasing, decreasing, or just changing direction.
When a cart is changing direction is it acceleration?
Consider a graph paper with Axis X and Y. Cart travel in X direction but suddenly, the cart change direction and so it must reduce velocity on X and increase velocity on Y. Net velocity might be the same but small acceleration and deceleration is apply in 2 dimension motion.
How do you find time with only distance and acceleration when Vi and VF are 0?
The amount of time it would take an object to travel a distance with constant acceleration depends on its initial velocity, according to the equation: d = vit + 0.5at2 Where d is displacement, vi is initial velocity, t is time, and a is acceleration. Note: if the object starts from rest, its initial velocity, logically, is zero.
Effect of acceleration due to gravity?
Acceleration due to gravity is the force that pulls objects towards the Earth. It causes objects to accelerate at a rate of 9.81 m/s^2 towards the ground. This acceleration is responsible for the feeling of weight that we experience, and it also affects the trajectory of objects thrown or dropped.
How is it possible to be accelerating at a constant speed?
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
How to find maximum centripetal acceleration?
That depends on the situation, on the problem you are trying to solve. If speed is constant, maximal centripetal acceleration occurs where the radius of curvature is smallest - for example, in the case of a parabola, at its vertex. If the radius of curvature is constant, maximum centripetal acceleration occurs when the speed is greatest (for an object reacting to gravity, that might be at the bottom of a circular path). In other cases, you have to get a general expression for the centripetal acceleration, and maximize it (using methods of calculus).
When Resultant velocity is calculated by using which two math functions?
The answer depends on what information you start with. For example, if you are given acceleration then you might integrate whereas if you are given displacement, you might differentiate.
How do you solve for acceleration when given distance and time?
you need a velocity unless its a falling object you should type in the problem statement and you might get a better answer
When you know both the speed and direction of an object's while it is in motion do you know the acceleration of the object?
Not necessarily. Knowing an object's speed and direction of motion does not automatically provide information about its acceleration, which is the rate of change of velocity. Acceleration depends on how much the velocity is changing over time, which might not be evident just from knowing the initial speed and direction.
What path might an object take that involves changing the velocity?
An object might change its velocity by accelerating, decelerating, changing direction, or a combination of these. For example, if a car starts from rest and accelerates along a straight road, it would experience a change in velocity. Another example is a ball thrown upwards experiencing a change in velocity as it goes up and then down due to the acceleration of gravity.
How can a graph showing deceleration differ from a graph showing acceleration?
A graph showing deceleration typically features a negative slope, indicating a reduction in velocity over time, while a graph showing acceleration displays a positive slope, indicating an increase in velocity. In a deceleration graph, the values of velocity decrease, often approaching zero, while in an acceleration graph, the velocity values increase. The shapes of the curves can also differ; a deceleration graph may show a smooth decline, while an acceleration graph might show a steep incline. Additionally, the axes may represent time and velocity in both cases, but the interpretation differs based on the direction of change.
What is speed at any given moment?
This is normally referred to as "instantaneous velocity" although if there is no change in velocity with respect to time - that is, no acceleration or deceleration - you might simply refer to it as "velocity".
What is a negative acceleration called?
You'll find a lot of people who call it "deceleration". But in real Physics, there's no such thing.There's only positive or negative acceleration, depending on whether the acceleration is inthe same or opposite direction compared to what you decided to call the positive direction.Negative acceleration is sometimes, but not always, associated with something that's slowing down.
