Question

difference between linear and curvilinear notion


rest and motion

scissor and knife

pulley and wheel and axel​

Answer 1

Explanation:

Linear and Curvilinear Motion

In linear motion all particles of human body travel the same distance during the same time. ... In curvilinear motion the trajectories of individual particles of the body are curved, although the orientation of the body in space does not change.

Rest and Motion

Rest: An object is said to be at rest if it does not change its position with respect to its surroundings with time. Motion: An object is said to be in motion if the position changes with respect to it surrounding and time.

Scissor and Knife

A knife can be used to pierce into objects but a scissor can usually not. A knife is usually sharper than a scissor And the tip is sharper than that of a scissor.

Pulley and wheel and axel

Pulley is used to change the direction of a rope or a chain. The actual rotation of the pulley wheel is a side effect. Wheel and axle are used to amplify rotational force. The force can be provided through a rope wrapped around the wheel, but the change of direction is a side effect.
