The speed of an object changes with time due to the presence of external forces acting on it, such as gravity, friction, or applied forces. These forces cause acceleration or deceleration, resulting in changes in speed over time.

The speed of an object changes with time due to the presence of external forces acting on it, such as gravity, friction, or applied forces. These forces cause acceleration or deceleration, resulting in changes in speed over time.
The speed of an object changes with time due to the influence of forces acting upon it. According to Newton’s second law of motion, the acceleration of an object is directly proportional to the net force applied and inversely proportional to its mass. Acceleration is the rate of change of velocity, and since speed is a component of velocity, any force causing a change in speed results in acceleration. Forces such as gravity, friction, or applied external forces can alter an object’s speed, leading to dynamic motion and reflecting the fundamental relationship between force, mass, and acceleration.
