  • 1

    Any object which projected by some means and continues to move due to its own inertia (mass)

    projectile

  • 2

    is a body which is given an initial velocity and is allowed to move under the sole influence of gravity.

    projectile

  • 3

    A projectile travels in a curved path called

    trajectory

  • 4

    is a combination of free fall and horizontal motions in which are independent of each other.

    projectile motion

  • 5

    refers to motion in which an object's velocity changes at a constant rate over time. This means the object experiences a consistent acceleration throughout its motion. In simpler terms, the speed of the object is either increasing or decreasing steadily with each second.

    uniformly accelerated motion

  • 6

    The acceleration remains the same throughout the motion.

    constant acceleration

  • 7

    The object's speed changes by a fixed amount in each unit of time.

    velocity changes uniformly

  • 8

    is one that is acted upon only by the gravitational force of the earth or when an object falls under the influence of gravity alone

    free fall

  • 9

    of the earth on a freely falling causes the object to be uniformly accelerated as it goes toward the surface of the earth.

    gravitational force

  • 10

    This force pulls the object toward the Earth's center, causing it to accelerate downward.

    gravity

  • 11

    In the presence of air, falling objects encounter _________ (or drag), which opposes their motion and affects their acceleration.

    air resistance

  • 12

    Objects with a larger surface area, such as a parachute, experience more air resistance compared to streamlined objects like a stone.

    shape and surface area

  • 13

    In a vacuum, where there is no air resistance, mass does not affect the acceleration of a free-falling object. All objects, regardless of their mass, fall at the same rate under gravity alone.

    mass (indirectly)

  • 14

    Factors affecting free falling bodies

    gravity , air resistance, mass (indirectly), height from which the object falls
