Therefore, more the mass more will be the inertia. It is easier to pull a lighter body than a heavier body. Why mass is sometimes called coefficient of linear inertia? Which principle is involved in the working of a jet plane? Name the physical quantity that corresponds to the rate of change of momentum. Name the principle on which a rocket works.īody A is heavier than body Question Which has more inertia?Ī body is moving with uniform acceleration. What is the total momentum of a bullet and a gun before firing? Plot a graph between force applied on a body and the acceleration produced in the given mass, assuming that the magnitude of force is constantly changing. No, action and reaction act on different bodies. When two or more forces act on a body simultaneously, then the single force which produces the same effect as produced by all the forces acting together is known as the resultant force.ĭo action and reaction act on the same body? What did Galileo conclude on the basis of his experiments on the motion of objects?Ī body continues to move with the same velocity if no unbalanced force acts on it. When a body moves on flat surface, will its speed change? What do balanced forces usually do to a body?īalanced forces usually produce a change in the shape of the body. If the body is found to be accelerated, is the force acting on it balanced or unbalanced? The force exerted by an electrically charged body is called electrostatic force. The force acting between any two surfaces in contact and tending to oppose motion is called force of friction. The force produced by the impact of a fast moving object on another is called impact force.

It can deform a body, i.e., it can change its shape.ġ newton is the magnitude of force which produces an acceleration of 1 m/s2 in a body of mass 1 kg.

It can bring about the change in the state of motion of a body or.

When a force is applied to a body, what are the two essential effects it can produce? Which law of motion gives the measure of force?Ĭan every force produce motion in every object? This is because of the frictional forces acting opposite to the direction of motion. Why do bicycles begin to slow down when we stop pedalling? Name the scientist who proved for the first time that objects move with constant speed when no force acts on them.
