First law
What are newtons first law of motion?
Law of inerita
How does newtons second law of motion relate to force and acceleration?
newtons second law of motion states that force is equal to mass times acceleration.
how can newtons third law of motion be demonstrated in everyday life?
When you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
How does friction affect motion, and how can it be reduced?
Friction causes a force on a surface which is in the opposite direction to its motion. Friction can be reduced by the application of lubricants
What is the difference between mass and weight?
mass is the amount of matter in a object, weight is the measure of the force of gravity on an object.
what is newton first law of motion and how does it relate to the concept of inertia?
states that a body will remain in its state of rest or of uniform motion unless an unbalanced force acts on.
what are newtons second law of motion, and how does it relate to force, mass and acceleration?
Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows.
what is the relationship between action and reaction in newtons third law of motion?
Action & Reaction Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
how does newtons first law of apply to objects in space?
non-zero net force is required to change the velocity of an object.
how does newtons third law of motion apply to the movement of boats?
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
how can newtons first law of motion be demonstrated in everyday life?
if no external force acts on an object, then an object will continue to remain in motion forever.
how can newtons second law of motion be used to calculate the force needed to accelerate an object?
The acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass
what is newtons third law of motion, and how does it relate to the concept of action and reaction?
Conservation of momentum
how does newtons third law of motion apply to the movement of airplanes?
determine how to best power the aircraft.
how can newtons second law of motion be used to calculate the force needed to lift an object?
The law in this form gives the force necessary to accelerate an object of a certain mass. An alternate form of Newton’s second law can be written: The lift of a wing is proportional to the amount of air diverted down times the vertical velocity of that air.
what is the difference between a balanced and unbalanced force, and how do they relate to newtons first law of motion?
When forces are balanced, they cancel each other out, resulting in no change in motion for the object they are acting on. Unbalanced forces do not cancel each other out, and result in a change in motion for the object they are acting on.
What is the difference between weight and mass, and how do they relate to newtons second law of motion?
The weight of something depends on its mass and the gravitational field strength. Weight is measured in Newtons and mass is measured in kilograms. Weight is a force. And it's caused by the pull of gravity acting on a mass. Mass is the amount of matter in an object. Unlike weight, it's not a force.
how can newtons third law of motion be demonstrated?
We can readily see Newton’s third law at work by taking a look at how people move about. Consider a swimmer pushing off from the side of a pool, as illustrated below. A swimmer pushes on the wall with her feet, which causes the wall to push back on her feet due to Newton's third law.
how are newtons second and third laws of motion related?
Newton's Second Law of Motion defines the relationship between acceleration, force, and mass. Newton's Third Law of Motion states that any time a force acts from one object to another, there is an equal force acting back on the original object. If you pull on a rope, therefore, the rope is pulling back on you as well.
how can newtons first law of motion be demonstrated using a ball and a ramp?
An object sliding across a table or floor slows down due to the net force of friction.
How does newtons first law of motion apply to objects in motion and objects at rest?
the law on inertia.
how can the concept of momentum be used to understand newtons second law of motion, and how can it be conserved in a closed system?
the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
how does newtons third law of motion apply to the movement of objects in space?
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
how can newtons first law of motion be used to explain why seat belts are important?
Because, according to Newton's first law, an object in motion will remain in motion unless an unbalanced force acts on it. When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force. Seat belts hold you and passengers down, protecting them from their own inertia.
what is the difference between a force and a torque, and how do they relate to newtons third law of motion?
Torque is represented using Newton-meters, whereas force is represented using Newton. The force of any material depends on the mass and acceleration, while torque depends on the force angle.
