When a body is said to be moving with uniform acceleration if it experiences equal?
When a body is changing its velocity at a constant rate i.e. equal change in velocity in an equal interval of time, then the body is said to be moving with uniform acceleration. Example: the free-falling of an object.
What are the equations of motion of a body moving with uniform acceleration?
Any of four equations that apply to bodies moving linearly with uniform acceleration (a). The equations, which relate distance covered (s) to the time taken (t), are: v = u + at s = (u + v)t/2 s = ut + at2/2 v2 = u2 + 2as where u is the initial velocity of the body and v is its final velocity.
When an object is moving with uniform acceleration what will be its acceleration?
An object moving at uniform or constant velocity has zero acceleration because there is no change in velocity. Q. If a body is moving with uniform velocity in a given direction its acceleration will be zero.
What does it mean when an object has uniform acceleration?
Translation: If an object’s speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration.
What is the SI unit of retardation?
Answer: The SI unit of Retardation (m/s²) meter per second squared. According to the definition, Acceleration can be defined as the rate of change of the velocity of any object. Retardation is the total opposite of acceleration i.e., negative acceleration.
What is an example of uniform motion and uniform acceleration?
An example of uniform accelerated motion is the motion of a freely falling body and a vertically thrown up body. Another example of uniform accelerated motion is a ball rolling down an inclined plane. If a body’s velocity changes at a constant rate, it has uniform Acceleration.
What are the 3 equations of uniform motion?
The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²
What is the SI unit of acceleration?
The SI unit of acceleration is metres/second2 (m/s2). Force (F), mass (m) and acceleration (g) are linked by Newton’s Second Law, which states that ‘The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass’.
What is the another name of negative acceleration?
The negative of acceleration is also known as deceleration or retardation.
What is the formula for uniform acceleration?
The first kinematic equation is v = v 0 + a t , where v is the final velocity, v is the initial velocity, a is the constant acceleration, and t is the time. It is a rearranged expression from the definition of acceleration, a = v − v 0 t .
When a body is said to be in equilibrium if acceleration is?
A moving object is in equilibrium if it moves with a constant velocity; then its acceleration is zero. A zero acceleration is the fundamental characteristic of an object in equilibrium.
Is the body said to be in equilibrium if it experiences linear acceleration?
A simple mechanical body is said to be in equilibrium if it experiences neither linear acceleration nor angular acceleration; unless it is disturbed by an outside force, it will continue in that condition indefinitely.
In what condition acceleration produced on a moving body is equal to zero?
Acceleration of an object can be zero when it is moving with a constant velocity. Since velocity is constant, there will be no change in velocity and so there will be no acceleration.
What happens to the motion of a body if the forces acting on it are equal and opposite?
When two equal and opposite forces are acting on a moving body, the motion of the body is not affected, it remains unchanged. it is because the net force acting on the object is zero.
