Question

i. Motion of your hands while running. ii. Motion of a horse pulling a cart on a straight road. V. Motion of a train on a straight bridge. iii. Motion of a child in a merry-go-round. iv. Motion of a child on a see-saw.​

Answer 1

V. Motion of a train on a straight bridge.

Answer 2

Answer:

Rectilinear motion

Rectilinear motion

Rectilinear motion

Rotational motion

Uniform motion

Explanation:

Linear motion, also called rectilinear motion, is one-dimensional motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

Linear velocity is the measure of “the rate of change of displacement with respect to time when the object moves along a straight path.” It is a vector quantity. Dimension formula of linear velocity is [M]0[L]1[T]-1. Linear and angular velocities are related to the speed of an object based on the perspective chosen.

Linear Kinetic Energy. If an object has a velocity or speed v,v, then its kinetic energy is: K, equals, one half, m, v, squared. K=21mv2. This is called linear kinetic energy. Note that the equation is still valid when the object is not travelling in a straight line.
