Q

It is a vector quantity defined as the rate at which an object changes its velocity.

A

Acceleration

17
Q

The acceleration vector is constant and lies along the line of the displacement vector so that the directions of v and a can be specified with positive and negative signs.

A

Uniformly Accelerated Motion

18
Q

It is when an object moves in a straight line.

A

Linear Motion

19
Q

It is when two objects move in a straight line parallel to each other.

A

Rectilinear Motion

20
Q

It is a branch of physics under classical mechanics that deals with motion of a body considering forces and masses.

A

Kinematics

21
Q

It is a falling body or a body thrown vertically upward or downward is a special case of uniformly accelerated motion.

A

Free-falling body

22
Q

It is a force that exist between two different bodies.

A

Gravity

23
Q

It is a force of attraction between two bodies and is very much independent on their mass.

A

Gravity

24
Q

He is the first to conclude that all falling bodies, regardless of their masses, will fall with constant acceleration, denoted by G.

A

Galileo Galilei

25
Q

Who made the Law of Universal Gravitation?

A

Isaac Newton

26
Q

It states that the attractive gravitational force between two masses is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
