Motion In One Dimension
Cards in this deck (14)
- 1RestWhen a body does not change its position with respect to surroundings.
- 2MotionWhen a body changes its position with respect to its surroundings.
- 3Scalar QuantitiesThe quantities, which are expressed only in magnitude, but not in direction.
Eg.Mass,length,time,temperature,area, volume - 4Vector QuantitiesThe quantities which are expressed in magnitude as well as direction.
Eg.displacement,velocity,acceleration,
force - 5DistanceThe length of path travelled by a moving body over a certain period of time.
- 6DisplacementThe shortest distance between the initial and the final position of a body in a specified direction.
- 7SpeedRate of change of motion
- 8Uniform SpeedWhen a body covers equal distances, in equal intervals of time(however small may be the intervals of time.
- 9Variable SpeedWhen a body covers unequal distances in equal intervals of time.
- 10Average SpeedThe ratio of the total distance travelled by the body to the total time taken by the body.
- 11Instantaneous SpeedThe speed of a body at some particular moment, when the body is moving at variable speed.
- 12AccelerationThe rate of change of velocity,
- 13Deceleration/Retardation/Negative AccelerationThe rate of change of velocity when the velocity is decreasing.
- 14Acceleration Due To GravityThe acceleration of a freely falling body, under the action of gravity of Earth.
