Q
What is gravitational field strength
A
The force of gravity on an object of mass
1
Q
And object is falling freely what is the resultant force acting on it
A
Gravity
2
Q
What is drag force on an object?
A
A force opposing the motion of an object due to fluid flowing past the object as it moves
3
Q
What is the terminal velocity
A
The velocity reached by an objects when the drag force on it is equal and opposite to the force making it move
4
Q
Why does an object in a fluid initially accelerate
A
There is a resultant force acting on it
5
Q
What eventually happens in object falling in a fluid
A
It will reach terminal velocity because the resultant force becomes zero
