Uniform motion describes an object that is moving in a specific direction at a constant speed. While uniform motion typically describes objects moving in a straight line, uniform circular motion consists of an object moving in a perfect circle at a constant speed.
Uniform motion describes a small set of circumstances because, in real life, most movement is not observed at a constant speed or direction. When an object travels in a straight line in uniform motion, the distance it has traveled can be calculated by multiplying the velocity by the time it took to travel the distance. Any object that moves with deviations in its speed or direction is said to be undergoing non-uniform motion.Learn More
When an object reaches its terminal velocity, it can no longer accelerate, so its acceleration becomes zero, and it falls at a constant speed. As an object falls freely through the air, it has two forces acting upon it: gravity and drag.Full Answer >
The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.Full Answer >
The path taken by a flying object in motion on the surface of the Earth is called a parabola. A parabola is a symmetrical arc, and the trajectory of flying objects with negligible air resistance in a gravitational field, as on the surface of the Earth, follows this path.Full Answer >
The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.Full Answer >
