What is known as accelerated motion?
In a circular motion, there is a continuous change in the direction of motion. The velocity changes when the direction changes. Therefore, circular motion is an accelerated motion.
What is accelerated motion explain with example?
Example:Suppose a car starts off from rest (initial velocity is zero) and its velocity increases at a steady rate so that after 5 sec its velocity is 10 m/s ,then the car is said to have an acceleration of 10-0/5= 2m/s square and motion is said to be accelerated motion.
Why is it called accelerated motion?
When a body moves in a circular path its direction of motion changes continuously. So, even body moves at a constant speed, its velocity is not constant. Thus, the velocity of a body moving in a circular path at a constant speed changes continuously. The change in velocity gives rise to acceleration in the moving body.
What is accelerated motion class 9?
acceleration. and this kind of motion is called accelerated motion. A body has uniform acceleration if it travels in a straight line and its velocity increases by equal amount in equal intervals of time for example freely falling bodies, motion of ball rolling down the inclined plane etc.
What is meant by circular motion?
In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. Since the object’s velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation.
Is a uniform circular motion accelerated motion explain?
When a body is in uniform circular motion, the speed of the body remains same or constant but the direction of the velocity of the body changes with respect to time. The change in the direction of the velocity of the body with time is called acceleration. So, a uniform circular motion is an accelerated motion.
What are 3 types of acceleration?
Any change in the velocity of an object results in an acceleration: increasing speed (what people usually mean when they say acceleration), decreasing speed (also called deceleration or retardation ), or changing direction (called centripetal acceleration ).
What is accelerated motion explain with necessary graph?
It is the rate of change of velocity with time. The only two ways to accelerate is by changing the speed or change in direction or change both. It is a vector quantity. If the velocity of the object increases with time, its acceleration increases.
Why is circular motion accelerated?
Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves at a constant speed, its velocity is not constant. Therefore, circular motion is an acceleration motion even when the speed remains constant.
Is uniform motion accelerated motion?
What is acceleration and types?
Acceleration is the rate of change of velocity with time. Acceleration occurs anytime an object’s speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. Average acceleration is determined over a “long” time interval.
