Worked practice questions

An object in flight after being thrown or projected is called a:

  1. Projectile
  2. Projection
  3. Protractor
  4. Propellant
Show answer and solution

Correct answer: A. Projectile

1. A football or a cricket ball in flight is an example. 2. Such an object is called a projectile. 3. So the correct answer is projectile. _Source: syllabus Physics Part I, Ch 4 'Motion in a Plane'_

Projectile motion is treated as the result of how many components?

  1. Nine
  2. Two
  3. Ten
  4. Six
Show answer and solution

Correct answer: B. Two

1. The motion splits into independent directions. 2. It is the result of two separate, simultaneously occurring components. 3. So the correct answer is two. _Source: syllabus Physics Part I, Ch 4 'Motion in a Plane'_

The horizontal component of projectile motion has:

  1. No acceleration
  2. No association
  3. No adjustment
  4. No adaptation
Show answer and solution

Correct answer: A. No acceleration

1. Gravity acts only downwards. 2. One component is along a horizontal direction without any acceleration. 3. So the correct answer is no acceleration. _Source: syllabus Physics Part I, Ch 4 'Motion in a Plane'_
