Motion and Movement

What is the difference between rectilinear and curvilinear motion?

• Rectilinear motion is circular, while curvilinear motion is straight.

• Rectilinear motion is two-dimensional, while curvilinear motion is three-dimensional.

• Rectilinear motion is along a straight line, while curvilinear motion is along a curved path.

• Rectilinear motion is constant, while curvilinear motion is variable.

Explain the concept of periodic motion.

• Periodic motion is a type of motion that repeats at regular intervals.

• Periodic motion is a type of motion that has no pattern.

• Periodic motion is a type of motion that speeds up over time.

• Periodic motion is a type of motion that only occurs once.

Give an example of translational motion.

• A person standing still

• A bird flying in the sky

• A car moving along a straight road

• A boat floating on water

Describe the motion of a pendulum.

• The motion of a pendulum is up and down

• The motion of a pendulum is side to side

• The motion of a pendulum is back and forth swinging.

• The motion of a pendulum is circular

What is circular motion and provide an example.

• Circular motion is the movement of an object in a circular path around a fixed point. An example is a car moving around a roundabout.

• An example of circular motion is a bird flying in a straight line.

• Circular motion is the movement of an object in a zigzag path around a fixed point.

• Circular motion is the movement of an object in a straight line around a fixed point.

Define oscillatory motion and give an example.

• A car moving in a straight line

• An example of oscillatory motion is a pendulum swinging back and forth.

• A ball rolling down a hill

• A person walking in a circle

Explain the difference between linear and angular motion.

• Linear motion is along a line, while angular motion is around a point.

• Linear motion is two-dimensional, while angular motion is three-dimensional.

• Linear motion is constant, while angular motion is variable.

• Linear motion is circular, while angular motion is straight.

What is vibratory motion and provide an example.

• Vibratory motion is a type of motion characterized by linear movement. An example of vibratory motion is a car driving on a straight road.

• Vibratory motion is a type of motion characterized by rotational spin. An example of vibratory motion is a spinning top.

• Vibratory motion is a type of motion characterized by periodic oscillations around an equilibrium point. An example of vibratory motion is a pendulum swinging back and forth.

• Vibratory motion is a type of motion characterized by random movements. An example of vibratory motion is a person jumping up and down.

Describe the motion of a rotating wheel.

• The motion of a rotating wheel is purely vertical.

• The motion of a rotating wheel involves back and forth movement only.

• The motion of a rotating wheel involves circular paths of each point on the wheel around the center, creating linear and angular velocity.

• The motion of a rotating wheel does not involve any velocity.

Give an example of reciprocating motion.

• Rotating of a wheel

• Piston movement in an engine

• Swinging of a pendulum

• Linear motion of a train
