The type of motion in which the object travels in a straight line with uniform speed, is called Uniform motion. This means that the velocity of the body remains constant as it covers equal distances in equal intervals of time. In the case of uniform rectilinear motion, the acceleration of the body will be zero.

What is uniform acceleration explain with example?
Uniformly Accelerated motion : When a body moves along a straight line and its velocity increases by equal amounts in equal interval of time then the motion is called uniformly accelerated motion. E.g.:- Motion of a freely falling body.
What is non uniform acceleration in physics?
An object is said to be with nonuniform acceleration if the velocity of the object changes by unequal amounts in equal intervals of time. Velocity-time graph for the Non-uniform acceleration is a curved line. Velocity-time graph for the Non-uniform acceleration is a curved line.
What is the simple definition of uniform motion?
Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
What is uniform acceleration formula?
Summary. Acceleration that does not change in time is uniform, or constant, acceleration. The equation relating initial velocity, final velocity, time, and acceleration is v f = v i + a t .
What is uniform and non uniform acceleration?
Uniform acceleration is change of equal velocity in equal intervals of time. Non Uniform acceleration is change of non-equal velocity in equal intervals of time.
What is the difference between uniform acceleration and constant?
In constant acceleration the body moving in a particular direction does not change its direction whereas in uniform acceleration the particle covers an equal distance in equal duration of time hence in both the situation acceleration of the body is zero.
What is the difference between acceleration and uniform acceleration?
Or we can define it as an acceleration in which its magnitude and direction don’t change with time. For example, the motion of a freely falling body is an example of a body travelling with uniform acceleration. The acceleration, in this case, is the acceleration due to gravity (g).
What is difference between uniform and non uniform velocity?
Uniform velocity: When an object covers equal (similar) displacement in equal (similar) intervals of time then it is called uniform velocity. Non-uniform speed: When an object covers unequal or different distances in equal (similar) time intervals then it is referred to as non-uniform speed.
Is uniform acceleration zero?
Motion with constant velocity is just a special case of motion with uniform (i.e. zero) acceleration.
Does uniform acceleration means constant velocity?
We know that Uniform Acceleration means that Acceleration remains constant, its change in Velocity will be constant over a period of time. Whereas in the non Uniform Acceleration the change in Velocity will not be the same. The direction of Velocity and the magnitude of the Acceleration will be changing with time.
What is uniform speed velocity and acceleration?
if both its magnitude and direction do not change with time then it can be said that the body is at uniform velocity. The rotation of the moon around the earth is an example of uniform motion. Acceleration is defined as the rate of change of velocity and is an example of a vector quantity.
What is uniform and non-uniform motion give examples?
When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.
What is the meaning of uniform and non-uniform motion?
If the speed of an object moving along a straight line keeps changing, its motion is called non – uniform. An object moving along a straight line with a constant speed is said to be in uniform motion.
What is uniform motion and non-uniform motion only definition?
An object covers equal distance which is equal interval of the time then object is said to have uniform motion. An object covers the unequal distance which is equal intervals of time then the object is said to have non-uniform motion.
What is the value of uniform acceleration?
The acceleration of body moving with uniform velocity is zero, because there is no change in velocity. Solve any question of Motion in a Straight Line with:- Patterns of problems. > 0.
Why uniform motion is accelerated?
Yes, uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion.. Due to this it is considered as accelerated motion.
What is uniform velocity?
Definition of Uniform velocity – A body when covers an equal distance with an equal interval of time, this condition of the velocity is known as uniform velocity. Or, we can say that when the direction and magnitude of speed of a body do not change with time, then the body is said to be at uniform velocity.
What is non uniform acceleration with example?
Non-uniformly accelerated motion: When a feather falls down in heavy storm, then the velocity of the feather decreases sometimes and sometimes it increases in unequal amounts in equal intervals of time. Thus it can be referred to as an example of non-uniformly accelerated motion.
What are 3 types of acceleration?
Answer: The three types of acceleration are 1) Change in velocity 2) Change in direction 3) Both change in velocity and direction .
What is non uniform velocity?
Non-uniform Velocity : When an object covers unequal distances in equal intervals of time in a specified direction, or if the direction of motion changes, it is said to be moving with a non-uniform or variable velocity. e.g., revolving fan at a constant speed has variable velocity.
What is uniform velocity with example?
When the body is moving with increasing velocity with equal interval of time then the body is said to be in uniform velocity and the example for such is rotational motion of the earth.
What is difference between uniform velocity and constant velocity?
Constant velocity is the velocity whose direction as well as magnitude remains constant. Uniform velocity is the velocity whose magnitude(only) increases with equal intervals of time.
What is the difference between uniform acceleration and non uniform acceleration with example?
Examples of uniform acceleration include constant speed in a straight line and an object affected by gravity. A ball thrown upwards and falling back does not have non-uniform acceleration: it has a directed motion and its speed changes, but the change is constant, so the acceleration is uniform.
What is the SI unit of uniform velocity?
The SI unit of velocity is metres per second (m/s).
