A block of mass m is attached to a massless spring of spring constant k This system is accelerated upward with acceleration a Find elongation spring?
The elongation of the spring in this system can be calculated using Hooke's Law, which states that the force exerted by the spring is directly proportional to its elongation. The force exerted by the spring is equal to the sum of the force due to gravity and the force required to provide the upward acceleration. By equating these forces and solving for the elongation, you can find the elongation of the spring in this system.

What is unformly accelerated motion?
Uniformly accelerated motion is when an object moves in a straight line with a constant acceleration. This means that the object's velocity is changing at a constant rate over time. An example of this is an object falling due to gravity, where its acceleration is constant at 9.8 m/s^2.
Can a body move with a constant velocity in an accelerated motion?
No. The definition of acceleration is change in velocity.
Can an object be accelerated if it is moving with constant speed?
No, an object cannot be accelerated if it is moving with constant speed. Acceleration is the rate of change of velocity, so if the speed is constant, there is no change in velocity, and therefore no acceleration.
What is the difference between constant motion and accelerated motion?
Constant motion occurs when an object maintains a constant speed and direction, while accelerated motion involves a change in speed or direction, resulting in an acceleration. In constant motion, there is no change in velocity, whereas in accelerated motion, velocity changes over time.
What is acceleration due to the gravity and uniform accelerated motion?
Acceleration due to gravity is the constant rate at which an object falls towards the Earth, which is approximately 9.81 m/s^2. Uniform accelerated motion refers to an object moving with a constant acceleration, such as a car increasing its speed by a fixed amount every second.
If an object is being accelerated can its velocity be constant?
No. Acceleration is any change of velocity.But its speed can be constant.

Is the vertical motion of a projectile accelerated?
Yes, the vertical motion of a projectile is accelerated due to the force of gravity acting on it, pulling it downward towards the Earth. This acceleration is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth.
Is uniform circular motion accelerated?
Yes, uniform circular motion involves constant speed but changing direction, which means there is acceleration present in the form of centripetal acceleration directed towards the center of the circular path.
What is the application of uniformly accelerated motion?
Uniformly accelerated motion is used to describe the motion of an object moving with a constant acceleration, such as a falling object under gravity. This concept is applied in physics to analyze and predict the motion of objects in free fall, projectile motion, and other scenarios where acceleration is constant. It helps in calculating the displacement, velocity, and acceleration of an object over time.
Is average acceleration equal to instantaneous acceleration for a uniformly accelerated car?
Average acceleration will be equal to instantaneous acceleration when an object has an uniform acceleration throughout its motion. Example : A car accelerating at 1m/s2 uniformly in a straight line.
Give reason why uniform circular motion is considered as accelerated motion?
Because within circular motion, acceleration is constant
Can an object be accelerated if it has a constant speed?
Yes. Acceleration means either speed or direction is changing. If direction is changing,then that's acceleration, even if speed is constant.
