Movement is a change in position over some time.
Speed is the rate at which you move.(i.e. 40mph)
Velocity is an object's speed and direction.(i.e. 40mph north)
Acceleration is how much your velocity changes over some time.(i.e. 40m/sec/sec north)
The equation for acceleration is (Final Velocity - Original Velocity)/Time. Imagine a vehicle starting off driving at 0 m/sec, okay? In the next second, it's traveling at 1 m/sec. In the next second, it's traveling at 2 m/sec. In the third second, it's traveling at 3 m/sec, and so on. The vehicle is accelerating because it's velocity is changing. To be even more precise, the vehicle is accelerating at a rate of 1 m/sec/sec, or 1 meter per second per second. This means that every second, the velocity changes by one second.
Remember that acceleration is change in velocity over some time. So if your velocity changes, then you're accelerating. If you're moving at a constant speed, you don't really feel like your accelerating, do you? But in fact, you are. Keep in mind that if you change direction, you are also changing velocity, and so you are accelerating. Even when we are standing still on the Earth, we are accelerating relative to the sun and other heavenly bodies since the Earth is always rotating and changing direction.
Acceleration doesn't always mean going faster. You can also decelerate, which you can figure is similar to slowing down. Imagine being on a roller coaster. As you dropped down a giant slope, the velocity of the coaster got faster and faster; you were accelerating. After that giant slope you get ready for another one(not the cranking kind. this slope is like a [[User:TieMyShooes|TieMyShooes]] 01:37, 25 Feb 2008 (UTC)) The coaster is decelerating up the slope because rather than getting faster in velocity, it's getting slower. However, the velocity you got from going down the previous slope gives you enough momentum to push you up the next one and so on. Whoohoo, fun!
So to sum it up, acceleration can be changed by a)speed and b)direction, which we know as c)velocity. =D
What else can I help you with?
What is the rate at which speed or direction changes?
Acceleration
What happens to the acceleration of an object as its mass decreases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
What is the acceleration of a 24 kg mass pushed by a 6N force?
Acceleration is 0.25m/s2 (A = force/mass).
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
What happens to the acceleration of an objects when the mass is cut in half?
The acceleration of an object is proportional to the net force acting on it. So if the force is reduced by half, the acceleration will also be halved. Of course, it will still be accelerating in the same direction as before, but not as quickly.
Does mass need to be changed to newtons to find the acceleration?
Mass can't be changed to newtons. The newton is a unit of force, not mass.In order to find the acceleration, you need to know the mass and the force.Then, the acceleration is (force) divided by (mass).
What is Changed direction?
acceleration in a direction that is not parallel to the direction you are moving
Why is changing direction a type of accleration?
There are two parts to acceleration: direction and speed. When either of these aspects are changed, then acceleration changes.
What agents would cause a change in centripetal acceleration?
Centripetal Acceleration is the ratio of the square of the velocity and radius ac=v2/r So if we change the velocity of the circulating object or change the radius of the revolution, centripetal acceleration is changed
How do you change centripetal acceleration?
Centripetal acceleration can be changed by altering the speed or direction of an object in circular motion. Increasing the speed will increase the centripetal acceleration, while changing the direction of motion will also change the centripetal acceleration.
What term explains wheather an objects velocity has increased or decreased over time?
You're fishing for "acceleration", but your description doesn't support that answer.Acceleration is also present if the direction of motion has changed, even if the speed(the size of velocity) hasn't changed.
How can mass and force be changed increase acceleration?
To increase acceleration: 1) Increase the force applied on the object, as acceleration is directly proportional to force. 2) Decrease the mass of the object, since acceleration is inversely proportional to mass according to Newton's second law of motion (F=ma). Increasing force or decreasing mass will result in a higher acceleration of the object.
What occurs to an object's direction when acted on by an unbalanced force?
Direction will be changed by the force caused acceleration, a=F/m.
Can the direction of he velovity of a body be change when its acceleration is constant?
That is what happening in case of a body moving uniformly around a circular path. Its speed ie the magnitude of velocity remains the same but every moment its direction is changed due to the constant acceleration known to be centripetal acceleration.
Which term explain whether an objects velocity has increased or decreased over time?
You're fishing for "acceleration", but your description doesn't support that answer.Acceleration is also present if the direction of motion has changed, even if the speed(the size of velocity) hasn't changed.Acceleration explains the change in an objects velocity over time.
Is Acceleration is the magnitude of average velocity?
No, acceleration is the rate of change of velocity with respect to time. It measures how quickly an object's velocity is changing. Average velocity, on the other hand, is the total displacement of an object divided by the total time taken.
Why did the acceleration slope change for each run?
The acceleration slope changed for each run because it is influenced by factors like the force applied, mass of the object, and any external forces acting on the object. These factors can vary between runs, leading to different acceleration slopes.
