While is not advisable to keep bucket of water insider room and leave it open?Īnswer: Yes it not advisable to keep bucket of water and leave it open inside the room, because the water may evaporate and cause supersaturated environment inside, which may cause difficulty in breathing. The center of gravity of a body in most cases is located at the center of the body.įundamentals of Physics questions and answers 11-20 The turning moment of force is the product of one of the forces and the perpendicular distance between the lines of the action of the tow forces, true or false?Īnswer: the center of gravity of a body is defending as the point through which its resultant weight acts. A system of two parallel, equal but opposite forces not acting along the same line is called what?. Examples Velocity, force, acceleration, displacement and many otherĪnswer: A scalar quantity is the one that has only magnitude but no direction. Does inertia of a body depend on its mass?Īnswer: Yes the inertia of a body depends on its mass, that is the bigger the mass of the body the bigger the bigger the inertial of the body while the smaller the mass of the body the smaller the inertial of the body.Īnswer: A vector quantity is the one that has both magnitude and direction. 
Why is it that when a stone of 200kg and feather of 0.2k, when dropped from the same height at the same time reach ground at the same time when they fall under the influence of gravity alone?Īnswer: Inertia is the tendency of a body to either remain in its state of rest or its uniform motion.When a heavy stone of 200kg and a feather of 0.2kg are dropped from up at the same time to fall under the influence of gravity alone, which one will reach ground first.Īnswer: Provided they fall under the influence of gravitational force alone as stated, both the stone and the feather will fall at the same time.Why is it that when you match a rug in your room you feel worn but when you match on the floor which is in the same room temperature with the rug you feel cold?Īnswer: It is because the cement floor is a good conductor of heat, therefore it conducts heat away from your feet far more than the rug in the say room temperature.
