What is a push or pull that can cause an object to accelerate or change direction

If an object pushes on another object, the 2nd object will push back

Which of the following could not be caused by a resultant force acting on an object?The object speeds upThe object maintains constant velocityThe object slows downThe object changes direction

By definition, acceleration is any change of:directionpositionspeedvelocity

According to Newton's Third Law of Motion, if you push gently on an object then it will push......Group of answer choicesgently on you but only if you are stationarygently on youharder on yougently on something else

1. Give two examples each of situations in which you push or pull to changethe state of motion of objects.2. Give two examples of situations in which applied force causes a change inthe shape of an object.3. Fill in the blanks in the following statements:(a) To draw water from a well we have to ——— at the rope.(b) A charged body ———— an uncharged body towards it.(c) To move a loaded trolley we have to ———— it.(d) The north pole of a magnet ———— the north pole of another magnet.© NCERTnot to be republishedSCIENCE1444. An archer stretches her bow while taking aim at the target. She thenreleases the arrow, which begins to move towards the target. Based onthis information fill up the gaps in the following statements using thefollowing terms:muscular, contact, non-contact, gravity, friction, shape, attraction(a) To stretch the bow, the archer applies a force that causes a changein its ——.(b) The force applied by the archer to stretch the bow is an example of ——— force.(c) The type of force responsible for a change in the state of motion of thearrow is an example of a ———— force.(d) While the arrow moves towards its target, the forces acting on it aredue to ———— and that due to ———— of air.5. In the following situations identify the agent exerting the force and theobject on which it acts. State the effect of the force in each case.(a) Squeezing a piece of lemon between the fingers to extract its juice.(b) Taking out paste from a toothpaste tube.(c) A load suspended from a spring while its other end is on a hook fixedto a wall.(d) An athlete making a high jump to clear the bar at a certain height.6. A blacksmith hammers a hot piece of iron while making a tool. How doesthe force due to hammering affect the piece of iron?7. An inflated balloon was pressed against a wall after it has been rubbedwith a piece of synthetic cloth. It was found that the balloon sticks to thewall. What force might be responsible for the attraction between the balloonand the wall?8. Name the forces acting on a plastic bucket containing water held aboveground level in your hand. Discuss why the forces acting on the bucket donot bring a change in its state of motion.9. A rocket has been fired upwards to launch a satellite in its orbit. Namethe two forces acting on the rocket immediately after leaving the launchingpad.10. When we press the bulb of a dropper with its nozzle kept in water, air inthe dropper is seen to escape in the form of bubbles. Once we release thepressure on the bulb, water gets filled in the dropper. The rise of water inthe dropper is due to(a) pressure of water(b) gravity of the earth(c) shape of rubber bulb(d) atmospheric pressureE X E R C I S E S© NCERTnot to be republished
