2.3 FREE FALL

An object experience __________________ if the motion of the object is affected only by gravitational force.

• free fall

• air resistance

• linear motion

• friction

The value for gravitational accelaration is __________________

• zero

• 9.81 ms - 1

• constant

• 9.81 ms - 2

A feather reach the ground slower than a stone in daily life (not in vacuum) due to __________________

What is free fall ?

• Acceleration of an object in free fall within a vacuum.

• One-dimensional motion along a straight line

• Any motion of a body where gravity is the only force acting upon it.

• Rate of change of the object's position with respect to a frame of reference and time

When a heavy object falls in the ______________ , air resistance can be ignored

• gravitational force

• gravitational field

• gravitational accelaration

• gravity

a free falling object does not experience the action of other forces such as air resistance or ________________.

Heavy objects fall and reach the ground ___________ than light object. (not in vacuum)

• faster

• slower

• same

An object experiences free fall if the motion of the object is affected only by ___________________ .
