Can you exp-lain circular motion with acceleration but no speed change to me??

Question

Please?? I try but I don't get it.

Answer 1

The short answer without any math is:

When you describe something's position, you say where it is.

Velocity is the rate at which something changes its position.
When you describe something's velocity, you say how fast it's going, AND IN WHAT DIRECTION. If all you are talking about is how fast it's going, it's just called "speed."

Acceleration is the rate at which something changes its velocity. Like velocity, it has both a rate and a direction. An object moving at 50 mph north does not have the same velocity as one moving at 50 mph west. And turning from north to west involves acceleration.

So an object moving in a circle is constantly changing its direction. Which means it is constantly changing its velocity. Which means it is constantly "accelerating." But it isn't changing it's "speed." Changing direction is enough to "accelerate" it.

Answer 2

In circular motion with no speed change we must understand no speed change as no speed absolute value change. But the direction of the motion changes. That means acceleration exists. The acceleration is perpendicular to the speed, so the speed does neither increase, nor decrease. Only the direction changes.

Answer 3

Acceleration means a change in velocity. Velocity has both speed and direction associated with it. Since anything in circular motion is constantly changing direction, it is accelerating. The speed however stays the same.

Answer 4

:) I had that problem too. Just remember that it is not a speed thing, but relate it to mass. Say of you had a younger sibling. Now if you were to swing them by the arms around in a circle. If you pull them closer to your body the speed remains the same but they are accelerating around the circle faster. if you let your arms out then the inverse is true. :) Hope that helps.

Newton's second law equation also reveals the relationship between acceleration and mass. According to the equation, the acceleration of an object is inversely proportional to mass of the object. In other words, the bigger the mass value is, the smaller that the acceleration value will be. As mass increases, the acceleration decreases. In fact, if the mass were increased by a factor of 2, the equation would predict that the acceleration would decrease by a factor of 2. Similarly, if the mass were decreased by a factor of 2, the equation would predict that the acceleration would increase by a factor of 2.

Answer 5

Acceleration is a vector (as opposed to a scalar), which means it has a direction as well as a magnitude. A change in acceleration occurs when either the magnitude of the acceleration changes, or the direction of the acceleration changes. When an object is moving in a circle, the direction is changing. You will find that the acceleration is towards the center of the circle.

Answer 6

According to my physics book, acceleration is a change in speed or direction. So you can accelerate in a circle, but that doesn't mean you change speed. If you change direction, you are accelerating. That's why there's accelerating circular motion that doesn't consist of speed changes.

I hope that helps.

Answer 7

Velocity is a vector. That means it includes both direction and quantity. Acceleration is defined as a change in velocity (speed OR direction) per unit time. So, even if the velocity is constant, any change in direction (like going around in a circle) is defined as acceleration.

Answer 8

i'm assuming you recognize the equation F=MA? enable's start up with this, accelleration relies upon on the two the course and speed. that's a vector. In cirtular action, the course it contantly changing. think of of swinging a ball on a string in a cirlce, in case you enable bypass while that is on the suited, it is going to fly off tangent to the circle it became making, give up it mutually as that is on the facet and it will fly off tangent returned, those are the two diverse guidelines. Now to the greater mathematical explation. i'm assuming you recognize the equation F=MA? rigidity=mass*acceleration. you have an merchandise in around action. mass would not exchange that's continuous. Now there are 2 forces appearing on it, the as quickly as swinging it arround (which if it have been going at a persevering with speed would be equivalent to the air resistance, making the F contained in the equation =0, so no acceleration) and a rigidity referred to as centripital rigidity. bypass decrease back to the ball on the string contained in the obove occasion. The string is exerting centripital rigidity, this is making it stay contained in the around course. This rigidity is the single that finally ends up contained in the equation by way of fact the rigidity conserving it in action is nearly insignificant. you have 3 issues. F(action) this is comparable to friction so F(action) - friction = 0 so we don't ought to concern approximately that. Mass, (we could call it .5 kg) and F(centripital) we could say that rigidity is 10 N. so now you have the equation F=MA or 10=.5A divide by utilising .5 and you get and accelleration of 20m/s even although the particularly speed has no longer replaced. was hoping I helped!

Answer 9

acceleration is not only change of speed, but also change of direction
