An object which is not moving is not experiencing any acceleration, other than the acceleration due to gravity, which, along with mass gives it its weight. The upward force (normal force) acting on the object is equal to but opposite to its weight, and all of the forces acting on the objects are in equilibrium so the net force is zero Newtons.
What else can I help you with?
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
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.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What happens when the same force is applied to an object?
If the object was stationery before any forces were applied it will remain stationery, and if it was moving it will remain moving but at a constant speed. There is no resultant force so the object experiences no acceleration.
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.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
If a moving object speeds upin what direction is the acceleration?
If a moving object is speeding up, the acceleration is in the same direction as the object's motion.
What effect does time have on the speed of a moving object?
Time does not directly affect the speed of a moving object. The speed of an object is determined by its acceleration and initial velocity. Time can impact the distance covered by the object over a period of time.
Why is an object moving in a constant speed undergoing?
An object moving at a constant speed is not undergoing acceleration because acceleration is a change in velocity over time. Since the object's speed is not changing, there is no acceleration.
What is the difference between tangential and centripetal acceleration?
Tangential acceleration is the change in speed of an object moving in a circular path, while centripetal acceleration is the acceleration that keeps an object moving in a circular path. Tangential acceleration affects the speed of the object, while centripetal acceleration affects the direction of the object's motion.
When an object is turning a corner what direction is the acceleration?
The acceleration of an object turning a corner is directed towards the center of the circle that the object is moving along. This acceleration is called centripetal acceleration and is responsible for changing the direction of the object's velocity, keeping it moving in a curved path.
He constant acceleration of an object moving in a circle is called?
centripetal acceleration
Can an object move without acceleration?
Yes. An object cannot begin to move without acceleration, but once it's moving, it needs no further acceleration to continue moving.
How the acceleration of a moving object can be increased?
In order to increase the acceleration of an object, you need to increase the net force applied to the object.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
If an object is moving in a circle with a constant speed, its acceleration is directed towards the center of the circle and is constant in magnitude. This acceleration is called centripetal acceleration and is required to keep the object moving in a circular path.
What is the difference between radial acceleration and centripetal acceleration?
Radial acceleration is the acceleration of an object moving in a circular path due to a change in direction, while centripetal acceleration is the acceleration towards the center of the circle that keeps an object moving in a circular path.
What is a moving object that has a velocity vector and acceleration vector in the opposite direction?
This is a moving object that is slowing down.
