A wooden block is placed on a table top. Name the forces acting on the block and draw a neat and labelled diagram to show the point of application and direction of these forces.

Newton's first law includes:

1. the definition of inertia
2. the definition of force
3. both (a) and (b)
4. none of the above

The property of an object by virtue of which it tends to retain its state of rest or of motion is called —

1. friction
2. inertia
3. force
4. mass

The property of inertia is more in —

1. a car
2. a truck
3. a horse cart
4. a toy car
