Newton's First Law
What does Newton's 1st law talk about?
An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
What is the Newton's second law of motion?
- The amount of force applied to an object affects it's speed. The acceleration of an object also depends on its mass.
State Newton's Third Law of Motion in your own words.
Newton's Third Law states that every action has a reaction of equal magnitude but in the opposite direction.
What is Newton's 1st law also known as?
Inertia
How can you calculate the mass with force and acceleration?
M=F/A
Provide an example from everyday life that illustrates Newton's Third Law.
An example could be when you walk on the ground. Your foot exerts a force backward (action), and the ground exerts an equal force forward (reaction), propelling you forward.
What will an object do when it cannot withstand the driving force?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction.
Give an example from everyday life that illustrates Newton's second law?
pushing a shopping cart with a greater force and the same mass, it will accelerate more quickly
Explain how Newton's Third Law relates to the concept of forces and interactions between objects.
Newton's Third Law is about the interaction between two objects. When Object A exerts a force on Object B, B simultaneously exerts a force of the same magnitude but in the opposite direction on A. It explains how forces always occur in pairs.
How does Newton's 1st law apply to everyday life?
break applied by a bus driver abruptly
An object with a mass of 7 kg accelerates 12.3 m/s2 when an unknown force is applied to it what is the amount of force?
87.5 N
Explore a scenario where the application of Newton's Third Law has significant consequences, either in engineering or physics
In engineering, the application of thrust in rocket engines is a scenario where the equal and opposite reactions are crucial. The expulsion of exhaust gases downward (action) propels the rocket upward (reaction), allowing it to overcome gravity.
What does newton's 1st explaining phenomena?
If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Suppose that a sled is rapidly at a rate of 2 m/s2. If the net force is tripled and the mass is halved, then what is the new acceleration of the sled?
12m/s2
Discuss instances where Newton's Third Law might not seem to hold true, and explain the underlying physics or conditions that could lead to deviations from the expected equal and opposite reactions.
While Newton's Third Law holds in many situations, there can be exceptions at extremely high speeds or on quantum scales. For example, at relativistic speeds, the conservation of momentum and mass-energy equivalence from Einstein's theory of relativity can introduce complexities that go beyond a simple equal and opposite reaction. Quantum mechanics also introduces probabilistic behavior at the microscopic scale, challenging a strictly deterministic interpretation of equal and opposite reactions.
