Motion In Plane Basic (Physics)

Question 1

What are scalar and vector quantities?

Answer 1

Scalar: Only magnitude (e.g., speed, distance).

Vector: Magnitude + direction (e.g., velocity, displacement).

Question 1

How do you add vectors geometrically?

Answer 1

Using triangle law or parallelogram law.

Place vectors tail to head and draw the resultant from start to end.

Question 2

What is projectile motion?

Answer 2

Motion under gravity in two dimensions with constant horizontal velocity and vertical acceleration.

Question 3

What is the equation for horizontal range in projectile motion?

Question 4

What is the maximum height reached in projectile motion?

Question 5

What is the time of flight of a projectile?

Question 6

What is uniform circular motion (UCM)?

Answer 6

Motion in a circle with constant speed but changing direction (velocity vector changes).

Question 7

What is centripetal acceleration?

Answer 7

Directed towards the center of the circle.

Question 8

How to resolve a vector into components?

Answer 8

Horizontal:

Vertical:
