In physics, motion is a change in position of an object with respect to time also on its reference point. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed. If the position of a body is not changing with the time with respect to a given frame of reference the body is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. This law is also referred to as the Law of Inertia which states that if the forces acting upon an object are balanced, then the acceleration of that object will be 0 m/s2. When a body experiences the same acceleration throughout an interval of time, its acceleration is said to be constant or uniform. Thus, this is called Uniformly Accelerated Motion.
Track and field is a sport which combines various athletic contests based on the skills of running, jumping, and throwing. The name is derived from the sport's typical venue: a stadium with an oval running track enclosing a grass field where the throwing and jumping events take place. Track and field is an example of linear motion occurs when an object or person travels in a straight line. According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or continue to move with uniform speed in a straight line, according to its initial condition of motion. In fact, in classical Newtonian mechanics, there is no important distinction between rest and uniform motion in a straight line; they may be regarded as the same state of motion seen by different observers, one moving at the same velocity as the particle, the other moving at constant velocity with respect to the particle. A body in motion may be said to have momentum equal to the product of its mass and its velocity. It also has a kind of energy that is entirely due to its motion, called kinetic energy.
Another sport related to track and field is swimming. Motion or change in position applied with respect to time, speed and to its reference point. Both sports perform uniformly accelerated motion in horizontal direction. With its relation to physics,if the position of a body is not changing with the time with respect to a given frame of reference. The body is said to be at rest, motionless, immobile,stationary or to have a constant position. An object’s motion cannot change unless it is acted upon by a force. The group’s advocate is that acceleration and momentum are needed in order to perform accurately in competitions. Warm-ups is also suggested to help the body work at its best and to prevent injuries.
