the answer to this question can be found using the following simple equation:
Vf = 9.8t + Vi
Vf = Velocity Final (m/s)
Vi = Velocity Initial (m/s)
t = Time (s)
For your specific problem, providing the object wasn't moving at the start of the 4 second period, the answer is 39.2 meters per second.
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
The velocity of free falling bodies does change due to gravity accelerating them towards the ground. However, in the absence of air resistance, the acceleration due to gravity causes the velocity to increase at a constant rate, resulting in a uniform change in speed over time. This creates the perception that the velocity is not changing, but in reality, it is increasing continuously.
The velocity of an object falling towards the surface of the Earth will increase by a rate of approximately 9.8 m/s² due to gravity. This acceleration would continue until the object reaches terminal velocity or impacts the surface of the Earth.
Yes. They accelerate (change the direction of their movement) towards Earth, and this may be labelled as "falling".Yes.

Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.
An object falling towards the Earth will stop accelerating once it reaches its terminal velocity, which is the maximum speed it can achieve due to air resistance. This happens when the force of air resistance is equal to the force of gravity acting on the object.
In a freely falling body, its velocity increases due to the acceleration caused by gravity. The acceleration is constant (9.8 m/s^2 on Earth), and the body's motion is only affected by gravity, not air resistance. The body's position changes continuously as it falls towards the ground.
The velocity of an object falling towards the surface of the Earth will increase approximately by 9.8 m/s every second due to gravity, assuming air resistance is negligible. This velocity will continue to increase until the object reaches its terminal velocity or collides with the Earth.
Gravity and velocity vectors in the proper ratio combine to make a state of perpetual falling towards the Earth that always misses
An object dropped from a height without any initial velocity, a skydiver falling towards the ground before deploying their parachute, and a rock falling off a cliff are all examples of free fall.
