1. A  conservation of momentumFalsemassnewtonsameTrue is that force which when acting on a body of mass 1 kg produces an acceleration of 1 m/s2 in it.
2. If the mass of a body and the force acting on it are doubled, then the acceleration is  conservation of momentumFalsemassnewtonsameTrue.
3. Physical principal involved in the working of a jet plane is the principle of  conservation of momentumFalsemassnewtonsameTrue.
4. The physical quantity which makes it easier to accelerate a small car than a large car is the  conservation of momentumFalsemassnewtonsameTrue.
Write true or false. (Q5 - Q10)
5. The linear momentum of a system of particles is always conserved.  conservation of momentumFalsemassnewtonsameTrue
6. A falling stone also attracts the earth.  conservation of momentumFalsemassnewtonsameTrue
7. The force of gravitation between two objects depends on the nature of medium between them.  conservation of momentumFalsemassnewtonsameTrue
8. The acceleration due to gravity acting on a freely falling body is directly proportional to the mass of the body.  conservation of momentumFalsemassnewtonsameTrue
9. Apparent weight of a person is always equal to his actual weight.  conservation of momentumFalsemassnewtonsameTrue
10. There is no gravity in the orbiting space station around the Earth. So the astronauts feel weightlessness.  conservation of momentumFalsemassnewtonsameTrue
