Is the rest a state of uniform motion?
Detailed Solution. The correct answer is the First law of motion. “An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force”. Above stated law is First law of motion.
Is uniform motion and rest same?
A body is said to be in uniform motion when it travels(moves from one place to another/ its position changes with respect to surrounding ) equal distances in equal interval of time . A body is said to be in rest when it does not change its position with respect to its immediate surrounding.
Why rest and uniform motion are treated as similar?
An object at rest can be considered to have uniform motion. Explanation: The object at rest has uniform speed of zero all the time and does not even change the direction . Hence, the velocity of an object rest is considered to be uniform .
Can the body be at rest in uniform speed Why?
Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.
Is required to change the state of rest or uniform motion of a body in a straight line?
Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, its state of motion can only be changed by Force application.
When a body is in rest or at uniform motion it is said to be in?
Under this condition, the body is said to be in translational equilibrium. The second condition ensures that the angular acceleration is zero i.e. either the body is at rest or it is moving with uniform angular velocity. Under this condition, the body is said to be in rotational equilibrium.
Can a moving body have uniform velocity and non uniform speed?
A moving body can have both uniform velocity and non-uniform speed at the same time.
What is 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.
When we say that the object is at rest its velocity is said to be?
An object at rest has zero velocity – and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
Can a body moving with uniform speed and non uniform acceleration?
A moving body having uniform speed can have non-uniform velocity. And, acceleration is defined as the time rate of change of velocity. So is true that the moving body with uniform speed can have acceleration. Was this answer helpful?
Can you have an object moving with uniform velocity but non uniform acceleration?
If the velocity of an object changes (i.e. velocity is non- uniform) in each unit of time is constant, then the object is said to be moving with uniform acceleration. So, a body can have uniform acceleration with non uniform velocity.
Is uniform speed and uniform velocity same?
When the speed of an object does not change then it is travelling with the uniform speed and when an objectwith uniform speed travelling without changing its direction then it is said to having uniformvelocity.
Is uniform acceleration zero?
If the body has uniform velocity, it means velocity is not changing. So the change in velocity is zero. In other words, its acceleration is zero.
Is uniform same as constant?
The word uniform means the “same in all cases”. Therefore, constant and uniform are often used interchangeably. Just be careful about where and when the sentence is used. For instance, if I say a car is accelerating uniformly in the xx-direction, then it has a constant acceleration in that direction.
Does uniform motion means the same as the uniform velocity explain?
No because uniform motion has only magnitude(scalar quantity) where as velocity has both magnitude and direction(vector quantity) so it can not be the same.
How uniform motion is different from non-uniform motion explain?
Uniform motion covers equal distance at an equal time interval. Non-uniform motion covers unequal distance at equal time interval. In uniform motion, the distance to time graph shows a straight line. In non-uniform motion, the distance to time graph shows a curved line.
How is uniform motion in a straight line different from uniform circular motion explain?
In uniform linear motion, the speed and direction of motion is fixed and so, it is not accelerated. Example- A car running on a straight road. In uniform circular motion, the speed is constant but the direction of motion changes continuously and hence, it is accelerated. Example- Motion of earth around the sun.
