Force Exe-1C Very Short Type Que
Concise Class 10 ICSE Selina Solutions
Que-1: Is it possible to have an accelerated motion with a constant speed? Name such type of motion.
Ans. Uniform circular motion is such type of motion. an accelerated motion with constant speed is possible. this motion is a such type of motion.
Que-2: Give an example of motion in which speed remains uniform, but the velocity changes.
Ans. the cases where speed is same. like artificial satellite motion. but velocity changes.
Que-3 Name the force required for circular motion. State its direction.
Ans. The direction of Centripetal force is always directed towards the center of circle. which means it is required centripetal force for circular motion.
Que-4: Is centrifugal force a real force?
Ans. The fictious force is a centripetal force we know so it is proved centripetal force is not a real force.
Que-5: State whether the following statements are true or false by writing T/F against them.
(a) Earth moves around the Sun with a uniform velocity.
Ans. (a) False
Reason — The Earth moves with uniform velocity. It follows an elliptical orbit, because earth move around the sun which means its speed varies as it travels around the Sun.
(b) The motion of Moon around Earth in a circular path is an accelerated motion.
(b) True
Reason — circular path is an accelerated motion because in a circular motion, the direction of velocity is continuously changing, which in turn causes change in acceleration because motion of moon around earth in a circular path.
(c) A uniform linear motion is unaccelerated, while a uniform circular motion is an accelerated motion.
(c) True
Reason — In uniform linear motion, an object moves in a straight line with a constant speed. there is no acceleration, on another side in uniform circular motion, an object moves in a circular path at a constant speed as it moves around the circle. and the direction of the object’s velocity continuously changes.
(d) In a uniform circular motion, the speed continuously changes because the direction of the motion changes.
(d) False
Reason —the speed of the object remains constant, but its velocity, which includes both speed and direction, changes continuously.
(e) A boy experiences a centrifugal force on his hand when he rotates a piece of stone tied at one end of a string, holding the other end in the hand.
(e) False
Reason — When the Rohan a boy rotates the stone tied to a string and holds the other end in his hand, the force experienced by his hand is centripetal force but not experienced, centrifugal force both are different.
Centrifugal force, on the other hand, is a fictitious force that appears to act outward from the center of rotation in a rotating reference frame Centripetal force is the force directed toward the center of the circular path, required to keep an object moving in a circular motion.
