Answer:
Distance- The length along a path between two points .
Velocity- The rate and direction at which an object moves .
Displacement- The net change in position of an object .
Vector- A measurement that has both magnitude and direction .
Speed- Measure of the rate at which an object changes position .
Momentum- The mass of an object multiplied by its velocity.
Explanation:
Vector: A physical quantity having both magnitude and direction is called Vector quantity. Example: Displacement, Velocity, Acceleration, Force etc.
On the other hand , quantity having only magnitude is called Scalar. Example: Distance, Speed, Time, Current etc.
Distance: The totle length of path traversed by a body in certain time is called distance. It is scalar quantity as it has only magnitude. SI unit of distance is meter.
Displacement: It is defined as change in position of a body in given period of time. Actually it is the distance between initial and final position along with given direction. So it is vector quantity. SI unit is meter.
Speed: The rate at which distance is traveled with respect to time is called speed.It is scalar quantity. SI unit is meter/second.
Velocity: It can be defined as rate of change in position or displacement with respect to time.It is vector quantity. SI unit is meter/second.
Momentum: The amount of motion contain in a body is the momentum. It is defined as product of mass and velocity. It is vector quantity. SI unit is kg.meter/second
Momentum=Mass×Velocity

Answer:
7.04 Hz
Explanation:
x(t) = A cos(wt)
v(t) = - wA sin (wt)
Vmax = wA
E = 1/2 * m * (Vmax)^2
E = 1/2*m*(wA)^2
f = w/ 2*pi
