What else can I help you with?
Is retardation positive or negative acceleration?
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
Why is the value of retardation is negative?
Retardation, often referred to as negative acceleration, is considered negative because it indicates a decrease in the velocity of an object over time. In physics, acceleration is defined as the rate of change of velocity, and when an object slows down, its change in velocity is in the opposite direction to its motion. This results in a negative value for retardation on the acceleration scale. Thus, it signifies that the velocity is decreasing rather than increasing.
When an object slows it has what acceleration?
Retardation or negative acceleration or deceleration.
Is the retardation means zero acceleration?
No, retardation refers to a negative acceleration, which means the object is slowing down. A zero acceleration means the object is moving at a constant velocity.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
A car has an initial speed of 10 M's The brakes are applied and the speed of the car is reduced to 5 M S in 2s Calculate the average value of retardation during the braking process?
The "retardation" is more correctly referred to as "acceleration".Since the car is slowing down, the acceleration is negative.Its average value is(change in speed) divided by (time for the change) = (5 - 10)/2= -2.5 m/sec2.
What is acceleration and retardation?
Acceleration is the rate of change of velocity over time, where an object is speeding up. Retardation, also known as deceleration, is the rate at which an object slows down or decreases in velocity over time.
Is retardation the opposite to accelaration?
I think the most accurate antonym for acceleration is deceleration.
Why not all motion the same?
Due to path in which it is made. Due to acceleration, retardation
How does retardation affect speed?
Retardation, also known as deceleration, is the process of slowing down an object's speed. When an object experiences retardation, its velocity decreases over time, resulting in a reduction in speed. This effect can be caused by various factors, such as friction or opposing forces, and is typically measured in terms of acceleration (negative acceleration). Consequently, the greater the retardation, the more rapidly the speed of the object diminishes.
What is uniform retardation?
Uniform retardation refers to a constant decrease in the velocity of an object over time, typically due to a consistent opposing force, such as friction or drag. In this scenario, the object's acceleration is negative and remains constant, leading to a linear decrease in speed until it eventually comes to a stop. This concept is often represented mathematically in kinematics equations, where the acceleration value is negative. It contrasts with uniform acceleration, where the velocity increases at a constant rate.
Is retardation is a vector?
Retardation is not a vector; rather, it refers to the process of slowing down or deceleration in motion. It is typically associated with a negative acceleration, indicating a decrease in velocity. While acceleration itself is a vector quantity (having both magnitude and direction), retardation specifically describes the effect of reducing speed, often in the opposite direction of motion.
