Answers
Answer:
2) Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. ... For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.
3). if an object changes its position with respect to its surroundings with time, then it is called in motion. ... Motion in a straight line is nothing but linear motion. As the name suggests, it's in a particular straight line, thus it can be said that it uses only one dimension.
4) When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.
5) Average speed is defined as the total distance travelled by the time taken whereas average velocity is defined as the displacement by the time taken. Since speed is a scalar quantity, the average speed is also considered as a scalar quantity while velocity is a vector quantity.
6). In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
Answer:
speed = distance/ time but velocity= displacement/ time
any object which changes its position with respect to the time and with respect to the reference object
the motion in which object moves on straight path is called rectilinear motion or straight line motion
the motion in which the speed of the object is constant and it covers equal distance in equal time is called uniform Motion
non uniform is opposite to uniform Motion.
