How is free fall related to uniformly accelerated motion?
“Free-fall” motion is a Uniformly Accelerated Motion that takes place in a vertical direction. The constant acceleration of the object is ALWAYS directed downwards due to the influence of Earth’s gravity; the acceleration due to gravity on Earth is referred to as “g”, and has a value of 9.8 m/s2.
What is free fall write equation of uniformly accelerated motion?
Answer: An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton’s second law of motion. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.
Is free fall a uniform motion?
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In a roughly uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body roughly equally.
Is a free falling body uniformly accelerated?
A freely falling body is moving under the acceleration due to gravity. Since the acceleration due to gravity is constant the body will be accelerated uniformly. Thus we can say that a freely falling body is having a uniformly accelerated motion. The answer is: uniformly accelerated motion.
Why is free fall called uniform acceleration?
The acceleration of free-falling objects is called the acceleration due to gravity, since objects are pulled towards the center of the earth. The acceleration due to gravity is constant on the surface of the Earth and has the value of 9.80 ms2 m s 2 .
Why is free fall motion considered a special case of uniformly accelerated motion?
Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.
What do you understand by relative velocity?
Definition of relative velocity : the vector difference between the velocities of two bodies : the velocity of a body with respect to another regarded as being at rest — compare relative motion.
Why is free fall called accelerated motion?
What type of motion is free fall motion?
Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
What is motion of freely falling bodies?
Explanation: The motion of a freely falling body is an example of uniformly accelerated motion. The motion of the body where the acceleration is constant is known as uniformly accelerated motion.
Are all falling bodies uniformly accelerated?
If air resistance and friction are negligible, then in a given location (because gravity changes with location), all objects fall toward the center of Earth with the same constant acceleration, independent of their mass, that constant acceleration is gravity.
