![]() ![]() As ” mass increases, inertia also increases. Loaded vehicles possess more inertia of motion. It is dangerous for loaded vehicles to negotiate a curve in the road without reducing speed. Also, it cannot be able to change its direction suddenly. In hammer throw, before the hammer is let go off, it is whirled along a circular path.Ī) An athlete doing a long jump-start his run from a distance.ī) A running elephant cannot change its direction suddenly.Ī) This activity helps to cover long distances by utilizing inertia of motion.ī) Mass of elephant is greater. When the coin on a Cardboard placed over a glass is struck, it falls into the glassģ. A man stepping down from a slowly moving bus stops after few steps of running.ģ. When the carpet is trapped, dust particle scatters.Ģ. A running athlete cannot stop himself abruptly at the finishing point.Ģ. When the branch of a mango tree is shaken mangoes fall.ġ. When a bus at rest starts suddenly, the standing passengers fall backward due to inertia of rest.Įxpand the table by finding more situations from daily life.ġ. When a running bus is suddenly stopped, the standing passengers fall forward due to inertia of motion. Inertia of motion : Inertia of motion is defined as the inability of a body to change its state of motion by itself. Inertia of rest: Inertia of rest is defined as the inability of a body to change its state of rest by itself. Inertia: The inability of a body to change its state of rest or of uniform motion along a straight line by its itself. Others will remain in the previous stage.ī) The passengers start to move forward due to the tendency to continue in its state of motion.Ĭ) It is due to the tendency to continue in the state of rest.ĭ) The passengers tend to fall backward due to the tendency to continue in their state of rest.Į) The passengers inside the vehicle have the tendency to move forward due to inertia of motion. Is pulled suddenly the brick remains in the same position as before.ĭ) When a bus moves forward suddenly from rest, the standing passengers tend to fall backward.Į) Accidents that happen to passengers who do not wear seat belts are more fatal.Ī) Only the coin at the bottom is thrown away. What do you observe? What is the reason?ī) When a running bus is suddenly stopped, passengers, standing in the bus show a tendency to fall forward.Ĭ) Place a small brick on a plank. Using the striker, strike out the coin at the bottom. Mass Transfer MCQ PDF arranged chapterwise! Start practicing now for exams, online tests.Ī) Place some carom board coins in a pile. The bottle falls in the direction of motion of the pa-per, due to inertia of motion of the bottle. Gradually increase the speed of pulling stop pulling when the bottle gains a certain speed. Bring the bottle into motion by pulling the paper slowly. Place a bottle on a thick paper with rough surface. Write down an activity to show inertia of motion. Inertia of motion is defined as the inability of a body to change it state of motion by itself. The bottle falls in the opposite direction fo the motion of paper. Place a bottle filled with water on a thick rough pa¬per as shown. Write down an activity to show inertia of rest. Inertia of rest is the tendency of a body to remain in its state of rest or its inability to change its state of rest by itself. Internal forces can not move an object, but only an external unbalanced force can cause motion.Įvery object continues in its state of rest or of uniform motion along a straight line unless an unbalanced external force acts on it. What if the same vehicle is pushed from outside. What will be the result when a man tries to move a vehicle by pushing it, standing inside the vehicle? The vehicle moves/the vehicle doesn’t move.
