Question 0

Centripetal acceleration

Answer 0

expression is obtained from analysis of constant speed circular motion by the use of similar triangles. From the ratio of the sides of the triangles:

Question 1

Acceleration

Answer 1

Acceleration is the rate of change of velocity with time. In everyday English, the word acceleration is often used to describe a state of increasing speed.

Question 2

Motion

Answer 2

Action or process of moving

Question 3

Displacement

Answer 3

displacement is the shortest distance from the initial to the final position of a point P. Thus, it is the length of an imaginary straight path, typically distinct from the path actually travelled by P. A “displacement vector” represents the length and direction of that imaginary straight path.

Question 4

Speed

Answer 4

Fastness

Question 5

Meter

Answer 5

Fundamental method of speed

Question 6

Velocity

Answer 6

Speed of something in a giving direction
