What is the value of the gravitational constant (G) in the provided scenario?
6.67 x 10^-11 Nm2/kg2
According to Newton’s first equation of motion, what is the formula to calculate velocity (v)?
v = u + at
If Mahendra starts with an initial velocity of zero and experiences an acceleration of 5.34 x 10^-9 m/s2, what will be his velocity after 1 second?
5.34 x 10^-9 m/s
How does the distance changing between Mahendra and Virat affect the gravitational force according to Newton's laws of motion?
Increases the gravitational force
Why does Mahendra's acceleration not remain constant as he moves towards Virat?
As the distance decreases, gravity increases
In the scenario described, what will be the effect on Mahendra's velocity with time as he moves towards Virat?
Velocity will increase with time due to increasing gravitational force
What is the direction of acceleration due to gravity on Earth?
Towards the Earth's center
What would happen if there were no gravity?
Objects would float in space
If the value of G (gravitational constant) was twice as large, what would be the effect on the gravitational force between two objects?
The force would increase
What determines the value of acceleration due to gravity on Earth?
Mass and radius of the Earth
If the mass of the Earth was twice as large and its radius half of what it is now, what would be the effect on the value of g on the surface of the Earth?
It would double
Does the acceleration due to gravity on Earth depend on the properties of the object?
No, it only depends on mass and radius of the Earth
What is the formula for calculating velocity using acceleration and time?
v = u + at
Why does an apple fall towards the earth but the earth does not move towards the apple?
Earth has more mass than the apple.
What happens to the moon and artificial satellites orbiting the earth due to the earth's gravitational force?
They revolve around the earth.
What determines whether an object will fall towards the earth or continue revolving around it?
The object's velocity
How is acceleration due to gravity defined?
Acceleration due to gravity is denoted by 'g'
According to Newton’s second law of motion, what does a force acting on a body result in?
Acceleration
