2. motion in one dimension

2-1: Position, Velocity, and Speed Position: is the location of the particle with respect to a chosen reference point that we can consider to be the origin of a coordinate system. Displacement: the displacement    of a particle is defined … إقرأ المزيد

2-7: Freely Falling Object

   In the absence of air resistance, all objects dropped near the Earth’s surface fall toward the Earth with the same constant acceleration under the influence of the Earth’s gravity.    When we use the expression freely falling object, we do … إقرأ المزيد

2-6: Analysis Model: Particle Under Constant Acceleration

the particle under constant acceleration. we generate several equations that describe the motion of a particle for this model. or:      (for constant    )  (2.13) Becouse velocity at cnstant acceleration varies linearly in time according to Equation (2.13), … إقرأ المزيد

2-4: Acceleration.

when the velocity of a particle changes with time, the particle is said to be accelerating. – The Average acceleration    of the particle is definded as the change in velocity    divided by the time interval    during which … إقرأ المزيد
