How far will a freely falling object have fallen from a position of rest when its instantaneous speed is 27 m per s?
Acceleration of gravity = 9.8 m/s2To reach speed of 27 m/s takes (27 / 9.8) secondsAverage speed during that interval = 1/2 (initial speed + final speed) = 27/2 m/s.Distance = (average speed) x (time) = (27/2) x (27/9.8) = 37.19 meters.
How far will a freely falling object have fallen from rest when its instantaneous speed is 10?
The distance fallen can be calculated using the equation ( d = \frac{1}{2}gt^2 ), where ( d ) is the distance fallen, ( g ) is the acceleration due to gravity (9.81 m/s^2), and ( t ) is the time taken to reach a speed of 10 m/s. To find ( t ), we can use the equation ( v = gt ), where ( v = 10 , m/s ). Solving for ( t ) gives ( t = \frac{v}{g} ). Substituting this value of ( t ) into the distance equation will give the distance fallen.
Is it true that Galileo expressed his observation on rate of speed of falling objects in a mathematical formula?
Yes, Galileo did express his observations on the rate of speed of falling objects in a mathematical formula. He showed that the distance fallen by a freely falling object is proportional to the square of the time it has been falling, which can be described by the equation d = 1/2 * g * t^2, where d is the distance fallen, g is the acceleration due to gravity, and t is time.
What changes in a freely falling body?
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.
Does an object that is freely falling have mass?
Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
How far will a freely falling object have fallen from a position of rest when its instantaneous speed is 6 ms?
1.8 m

What is the appropriate equation for how fast an object freely falls from a position of rest for how far that object falls?
The equation for the distance fallen by an object freely falling from rest can be calculated using the formula d = (1/2) * g * t^2, where d is the distance fallen, g is the acceleration due to gravity (approx. 9.81 m/s^2), and t is the time elapsed.

What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Where does the law of gravity operate?
Freely falling bodies
What are the factors affecting freely falling bodies?
force and gravity

Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
How far will a freely falling object fall from a position of rest in 5 sec?
A freely falling object will fall approximately 122.5 meters in 5 seconds assuming no air resistance. This value can be calculated using the formula d = 0.5 * g * t^2, where d is the distance fallen, g is acceleration due to gravity (approximately 9.81 m/s^2), and t is the time in seconds.
What is the direction of the acceleration of a freely falling body?
9.8 m/s2
