Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction.
That being said, you can accelerate an object without changing its speed by simply changing its direction.
A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
What else can I help you with?
What are the assumptions used to develop the kinematics model of circular motion?
The main assumptions in developing the kinematics model of circular motion are that the object is moving along a circular path at a constant speed, which implies uniform circular motion. Additionally, it is assumed that there is no tangential acceleration, meaning that the speed of the object remains constant. Finally, the assumption is made that the object's motion can be described using angular quantities such as angular displacement, velocity, and acceleration.
Can a body moving with uniform speed have variable velocity?
Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity
When can an object a constant speed but not a constant velocity?
If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.
What would be the shape of speed time graph of a body moving with variable speed?
Distance-time graph will show a straight line with a positive slope. Speed-time graph will show a horizontal line at the uniform speed. Acceleration-time graph will show a horizontal line at a = 0.
A ball is thrown vertically upward. What are its velocity and acceleration when it reaches its maximum altitude What is the acceleration of the ball just before it hits the ground?
At the maximum height the ball will be completely stopped from moving upward or downward; thus the speed of the ball would be 0 mph. The ball is only stopped for a split second and then it begins moving downward, then increasing at 9.81m/s^2 until it reaches maximum velocity.
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.
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.
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.
What kind of speed has no acceleration?
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
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 is the acceleration of an object that travels in a straight line at a constant speed?
The acceleration of an object moving in a straight line at a constant speed is zero. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity and thus no acceleration.
Can an object that move at a constant speed be accelerating?
No, an object moving at a constant speed cannot be accelerating. Acceleration is defined as a change in velocity over time, so if the speed is constant, there is no change in velocity and therefore no acceleration.
When the velocity of a moving object stays the same it has a?
an acceleration of Zero, and a constant Inertia.
What is the Direction of Acceleration of an object moving on any circular path at constant speed is pointed?
The direction of acceleration of an object moving on a circular path at constant speed is pointed towards the center of the circle. This acceleration is called centripetal acceleration and is necessary to keep the object moving in a curved path.
An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
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.
What is the difference between constant acceleration and constant velocity in terms of their impact on an object's motion?
Constant acceleration refers to a steady change in an object's velocity over time, while constant velocity means the object is moving at a consistent speed in a straight line. Constant acceleration will cause the object to speed up or slow down, while constant velocity will keep the object moving at the same speed without any change.
