If a rock is dropped from a bridge, its acceleration remains the same (9.8 m/s², the acceleration of gravity on Earth, no matter how heavy the rock is), and its speed increases at the rate of (9.8 meters per second for every second it falls).

The acceleration of the rock remains the same while the speed increases as the rock moves downwards.

The motion of an object dropped from a certain height is affected by Earth's gravitational influence.

  • The acceleration due gravity on the object will be constant throughout the motion.
  • The direction of this acceleration due to gravity is downwards.

The object's speed increases as the object moves downwards and it will eventually become maximum before the object hits the ground.

  • The direction of the object's speed is always in the direction of the object's motion.

Thus, we can conclude that the acceleration of the rock remains the same while the speed increases as the rock moves downwards.
