please can anyone help me with ittt

Answer:
Speed
Speed is simply the rate of change of motion.
Speed is the distance traveled by a body in a unit time.
Speed is a scalar quantity
Speed ascertains how fast a body moves.
Velocity
Velocity is a vector quantity.
Velocity is direction-aware and it is the rate of change of position of an object.
Velocity is the displacement covered by a body in a unit time
Velocity ascertains the object’s speed and the direction it takes while moving.
Answer:
What are the 3 equations of motion used for?
In case of uniform acceleration, there are three equations of motion which are also known as the laws of constant acceleration. Hence, these equations are used to derive the components like displacement(s), velocity (initial and final),
☺moving object is known to exhibit motion. Motion is a phenomenon that is very common in our daily life. For example, the car in which you travel moves, the air we breathe is in motion, the blood in our veins is in motion, the earth is in motion, the universe is moving and many more.
☺Three Equations of Motion are v = u + at; s = ut + (1/2) at² and v² = u² + 2as and these can be derived with the help of velocity time graphs using definition acceleration.
