Acceleration If an object is changing its velocity -whether by a constant amount or a varying amount - then it is an accelerating object. And an object with a constant velocity is not accelerating. The data tables below depict motions of objects with a constant acceleration and a changing acceleration.

rotation & torque Any time that the sign (+ or -) of the acceleration is the same as the sign of the velocity, the object will speed up. If the signs are opposite, the object will slow down. Acceleration is a vector defined by properties of magnitude (size or measurability) and direction.

How is acceleration defined? The velocity is changing over the course of time. In fact, the velocity is changing by a constant amount - 10 m/s - in each second of time. Anytime an object's velocity is changing, the object is said to be accelerating; it has an acceleration.

Newton's laws of motion (1) An object will remain at rest or continue with constant velocity unless acted on by an unbalanced force. (2) The rate of change of momentum (or acceleration for a body/object of constant mass) is proportional to, and in the same direction as, the force applied to it (force = mass ×1 acceleration).

- Acceleration indicates the rate of change of the object’s velocity (v G); i.e., the acceleration tells you how fast the object’s velocity is changing. The component of the acceleration that is parallel to the velocity (a || G) indicates the rate of change of the object’s speed. If a || Gis parallel to the velocity, then the object is speeding up; if a || is anti-parallel to the velocity, then the object is slowing down.

- The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion, e.g. 7001166666666666666♠60 km/h to the north.Velocity is an important concept in kinematics, the branch of classical mechanics that describes the motion of bodies.o have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path (the object's path does not curve).

Is there any difference between constant speed and uniform speed. what is constant velocity? Acceleration is a change in velocity. The change can be in direction only (such as centripetal acceleration during uniform circular motion). Under these circumstances, velocity is changing but speed is not. So constant speed does not imply zero acceleration.

- Whereas Acceleration of a body is  defined as change in Velocity of a body at a particular instant of  Time.     Acceleration = Final Velocity-Initial Velocity/Time   Now If Velocity is Uniform or Constant then Acceleration is Zero   The same difference as between velocity and position.

Constant acceleration & Constant acceleration equations Constant acceleration equations : Constant acceleration or deceleration is so common in Physics and in life that a special set of equations are derived to analyze the situations in which acceleration is constant, Those equations are called “Constant acceleration equations”.

Uniform Velocity A body is said to have uniform velocity if it covers equal distance in equal intervals of time in a particular direction, however the time intervals may be small. This means that if a body is traveling at a constant speed along a straight line (i.e, a particular direction) then it said to have uniform velocity.

Velocity The average velocity is always less than or equal to the average speed of an object. This can be seen by realizing that while distance is always strictly increasing, displacement can increase or decrease in magnitude as well as change direction.hus, a constant velocity means motion in a straight line at a constant speed.. For example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration.

Speed and Velocity Acceleration describes the rate at which velocity changes. Acceleration is a Vector. If an object is not changing direction you can describe its acceleration as the rate at which its speed changes. To determine the acceleration of an object, you must calculate its change in velocity per unit of time. acceleration=final velocity(speed)minus initial velocity divided by time EX: acceleration =.

Physics 1 Kinematics Notes Acceleration Acceleration is the rate at which velocity changes. In other words, knowing the acceleration of an object tells you how fast the velocity of the object is changing. Since velocity is the rate at which position changes, and acceleration is the rate at which velocity changes, acceleration is a rate of a rate.

The Meaning of Shape for a p-t Graph The shapes of the position versus time graphs for these two basic types of motion - constant velocity motion and accelerated motion (i.e., changing velocity) - reveal an important principle. The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object. Whatever characteristics the velocity has, the slope will exhibit the same (and vice versa). If the velocity is constant, then the slope is constant (i.e., a straight line).

The Acceleration of Gravity Recall from an earlier lesson that acceleration is the rate at which an object changes its velocity. It is the ratio of velocity change to time between any two points in an object's path. To accelerate at 9.8 m/s/s means to change the velocity by 9.8 m/s each second. If the velocity and time for a free-falling object being dropped from a position of rest were tabulated, then one would note the following pattern.
