state Newton’s First Law. You can paraphrase, or quote and include a citation:
Newton's First Law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue to move with the same velocity, unless acted upon by an external force. This principle was stated by Sir Isaac Newton in his book "Mathematical Principles of Natural Philosophy" in 1687.
can u quote it
"Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed." - Isaac Newton, "Mathematical Principles of Natural Philosophy" (1687)
another pls
"Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." - Isaac Newton, "Mathematical Principles of Natural Philosophy" (1687)
How did the Tug of War activity demonstrate Newton’s First Law of Motion?
The Tug of War activity demonstrates Newton's First Law of Motion through the concept of inertia. Inertia is the tendency of an object to resist changes in its state of motion. In the Tug of War, when both teams exert equal force and remain stationary, the rope remains at rest. This is due to the first law, which states that an object at rest will remain at rest unless acted upon by an external force. Similarly, if one team pulls harder than the other, the rope will move in the direction of the stronger force. This observation supports Newton's first law, as an object in motion will continue to move with the same velocity (or change its velocity) unless acted upon by an external force.
are elevators have unbalance or balance forces
Elevators experience balanced forces.
In an elevator, there are typically two main forces at play: gravity and the tension force exerted by the elevator cable. The force of gravity pulls the occupants downward, while the tension force of the cable pulls the elevator upward to counteract gravity.
When the elevator is at rest or moving at a constant velocity, these two forces are balanced. The tension force equals the force of gravity, resulting in a net force of zero. This balance of forces allows the elevator and its occupants to remain in a state of equilibrium.
However, during certain situations such as acceleration or deceleration of the elevator, the forces may become momentarily unbalanced. For example, when the elevator starts to move upward or downward, there will be a temporary imbalance between the tension force and gravity, resulting in a net force in the direction of motion. Once the elevator reaches the desired velocity, the forces balance out again.
how to elevators use newtons 1 law
Elevators utilize Newton's First Law of Motion to operate effectively and safely. Newton's First Law states that an object at rest will stay at rest, and an object in motion will stay in motion with the same velocity, unless acted upon by an external force.
When an elevator is at rest, it remains stationary due to the balanced forces of gravity and the tension force exerted by the elevator cable. As per Newton's First Law, the elevator stays at rest until an external force is applied.
When an elevator is called and the motor starts, it applies an external force to overcome the inertia and initiate motion. As a result, the elevator begins to accelerate in the desired direction. During this time, Newton's First Law applies as the elevator remains in motion with a changing velocity, due to the external force applied by the motor.
Once the elevator reaches the desired velocity, the motor adjusts its force to maintain a constant speed. At this point, the elevator stays in motion with a constant velocity, again adhering to Newton's First Law. The balanced forces of gravity and tension in the cable keep the elevator moving at a steady pace.
When the elevator reaches the intended floor and the motor stops, it applies an external force in the opposite direction to decelerate the elevator and bring it to a halt. Newton's First Law is once again in action as the elevator, due to its inertia, tends to remain in motion with the same velocity until acted upon by the external force of deceleration.
In summary, elevators rely on Newton's First Law to start, maintain, and stop their motion by applying external forces to counteract the inherent tendency of objects to stay at rest or in motion.
