Kinematics

Question 1

Define Terminal Velocity

Answer 1

Terminal velocity is the constant speed that a falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

Question 2

Define Projectile Motion

Answer 2

When a projectile thrown near the surface of earth, and it moves along a curved path under the influence of gravity only.

Question 3

What are the 3 assumptions when analyzing projectile motion.

Answer 3

acceleration due to gravity is constant at -9.81m/s^2, no horizontal acceleration and no air resistance.

Question 4

Kinematics equation without time

Answer 4

v^2=u^2+2as

Question 5

Kinematics equations with time

Answer 5

v=u+at and s=ut+1/2at^2
