Answer:
1) Average velocity: The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a Vector quantity. The SI unit is meters per second.
2) Inertia :a tendency to do nothing or to remain unchanged.
3) Momentum : the quantity of motion of a moving body, measured as a product of its mass and velocity.
=>the impetus gained by a moving object
4) Acceleration : the rate of change of velocity per unit of time.
5) Newton force : One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. ... The newton thus became the standard unit of force in the Système international d'unités (SI), or International System of Units. The newton is named after Isaac Newton.
6) Balanced force: Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an object, the object stays still or continues moving continues to move at the same speed and in the same direction.

Answer:
1.The total distance travelled within the total time taken
2. Inability of a body to stay rest or move in a uniform motion along a straight line.
3. product of mass and velocity
4. Change in velocity by time taken
5. The force needed to accelerate one Kg of mass of body at a rate of 1m/s^2
6. if F net is 0 then it's balanced... in other words... if the acceleration is 0... then it will be Balanced.
Hope you got me.
