Periodic Motion
Random Motion

Question 2

Distance vs displacement

Answer 2

Distance: Total path length traveled (scalar).
Displacement: Straight-line distance from initial to final position (vector)

Question 3

Distance traveled per unit time (scalar).

Answer 3

Speed

m/s
2
g≈9.8m/s² downward.

Question 12

An object remains at rest or in uniform motion in a straight line unless acted upon by an external force

Answer 12

Newton’s First Law (Law of Inertia)

Question 13

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
F=ma.

Answer 13

Newton’s second law

Question 14

For every action, there is an equal and opposite reaction.

Answer 14

Newton’s third law
