Sample questions

1. What is force?

   1. A push or pull on an object
   2. A type of energy
   3. The speed of an object
   4. The mass of an object
   Show answer

   Answer: A. A push or pull on an object

   Force is defined as a push or pull that causes an object to move or change its motion.

2. Which of the following is an example of friction?

   1. A book falling off a shelf
   2. Sliding a book across a table
   3. A car accelerating on a road
   4. A ball being kicked
   Show answer

   Answer: B. Sliding a book across a table

   Friction is a force that opposes motion. Sliding a book across a table creates friction between the book and the table.

3. What happens to the motion of an object when a net force is applied?

   1. It stops moving
   2. It starts moving
   3. It changes speed or direction
   4. It changes color
   Show answer

   Answer: C. It changes speed or direction

   When a net force is applied to an object, it can cause the object to either change its speed or change its direction of motion.

4. What is the relationship between mass and inertia?

   1. Mass increases inertia
   2. Mass decreases inertia
   3. Inertia has no relation to mass
   4. Inertia is another name for mass
   Show answer

   Answer: A. Mass increases inertia

   Inertia is directly related to mass; the greater the mass of an object, the greater its inertia, meaning it's more resistant to changes in motion.

5. What will happen to the speed of an object if friction acts on it?

   1. Increases
   2. Decreases
   3. Remains the same
   4. Stops
   Show answer

   Answer: B. Decreases

   Friction is a force that opposes motion, therefore it slows down the speed of moving objects.
