Extra Explaining Question - APPLICATION OF VECTORS

APPLICATION OF VECTORS

1. 1.

   Mr. Almasi was pulling a box by force acting at an angle θ with horizontal. Explain why the front edge lifts slightly.

   The applied force has a vertical component which reduces the normal reaction, causing the front edge to lift slightly.
2. 2.

   How can you separate scalars and vectors from mixed physical quantities?

   Scalars have magnitude only while vectors have both magnitude and direction.
3. 3.

   You travelled from Songea to Masasi. Explain relative motion using two scenarios.

   Motion depends on observer’s frame of reference. Inside bus passengers appear at rest but are moving relative to ground.
4. 4.

   Explain resolution of force on an inclined plane.

   Weight is resolved into two components: parallel and perpendicular to the plane.
5. 5.

   Explain relative velocity with examples.

   Relative velocity is velocity of an object as observed from another moving object.
6. 6.

   Explain triangle law of vector addition with diagram idea.

   If two vectors are placed head-to-tail, resultant is drawn from start of first to end of second.
