True or false Negative acceleration always means that a system is slowing down?
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
Would a force have to be applied in the same or opposite direction to stop a moving ball?
The opposite direction. To stop a moving object requires an acceleration in the direction opposite its motion.
How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
How could an object accelerate while still traveling at a constant speed?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
Is it impossible when an object moving in a straight line has no acceleration?
Yes, if an object is moving in a straight line and has no change in its speed or direction, then it has no acceleration. Acceleration is the rate of change of velocity, so if the velocity is constant, the acceleration is zero.
What force keeps an object moving in a circle. in what direction does this force act?
The Centripetal force keeps a object moving in a circle and its force and acceleration are directed toward the center of the circle
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
It is constant in magnitude. It is changing in direction.
Does the acceleration of a body moving in circular path remain constant?
If the speed of the object doesn't change, then yes.
What is the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
In toward the center of the circle.
What will be acceleration of a car moving in a circular motion with constant speed.?
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
What is to change direction?
acceleration in a direction that is not parallel to the direction you are moving
What is Changed direction?
acceleration in a direction that is not parallel to the direction you are moving
Which describe acceleration involving only a change in directions?
This type of acceleration occurs when an object is moving around a circle at a constant speed. As the object moves around the circle, the direction of its velocity is constantly changing. This type of acceleration is called centripetal acceleration. The direction of the acceleration is toward the center of the circle. I hope this answers your question. A car traveling 25 MPH turns 30-degrees to the left without losing speed -- it has accelerated.
Why is traveling in a circle at constant speed called acceleration?
Traveling in any direction, but moving is acceleration. if a particle moves in a circle and comes to the initial position, then the velocity would be zero. acceleration is a scalar quantity and not a vector quantity. answered by K.Sreram from India
He constant acceleration of an object moving in a circle is called?
centripetal acceleration
Is An object moving with a certain direction with an acceleration in the perpendicular direction?
There can be.
Why does centripetal acceleration occur?
Centripetal acceleration occurs because an object moving in a circular path is constantly changing direction, which requires an inward force to keep it moving in a circle. This inward force causes the centripetal acceleration, directed towards the center of the circle.
