Is a clock rotational motion?
Since the clock hands move in a circular direction, they are said to be in circular or rotational motion.
What type of motion is hands of clock?
The hand of the clock performs periodic motion. This is because the motion will repeat after a given interval of time. The motion of the hand of the clock can also be called as rotatory motion. The hand rotates about a fixed point at one end of itself.
Which is an example of rotational motion?
A person performing a Somersault, is an example of rotational motion. When we open a cap of any soda bottle, it jumps up in the air because of pressure released and is an example of rotational motion. Fan moving in the house, table fan, hand blender’s blades motion are all examples of rotational motion.
What is rotational motion and give an example?
Rotational motion can be defined as a motion of an object around a circular path, in a fixed orbit. … It can also be defined as the motion of a body, in which all of its particles move in a circular motion with a common angular velocity, about a fixed point—for example, the rotation of Earth about its axis.
Is the motion of a clock hand a uniform circular motion?
Yes, because its speed is constant at every instant.
Are hands of clock uniform motion?
The motion of a second hand in a clock has a constant speed and it covers equal distance at an equal interval of time but changes the direction. Hence the second’s hand of the clock is an example of non-uniform motion. The answer is Option (B): Uniform motion.
What are clock hands?
A clock hand is an arm that connects to the shaft on a clock movement that overlays over a clock dial face and points to the numerals or symbols on the clock face or watch that displays the time. Most clocks have a short hour hand a long minute hand and a long skinny second hand to display the time.
What type of motion is a pendulum in a clock?
Pendulum clock shows periodic type of motion. This kind of motion that repeats after a specific period of time is known as periodic motion. In the periodic motion, the movement made by these objects is called oscillation.
Which kind of motion is exhibited in clocks and watches?
Periodic motion of a pendulum has been used to make clocks and watches.
How many types of rotational motion are there?
Galaxies rotate in the Universe. All motion can be classified into three basic types: Translation , Rotation , and Vibration. A baseball translates along a parabolic path, rotates (spins) about its center, and vibrates when it hits a bat.
