Newton laws

• The second law of motion describes how forces affect acceleration.
• Newton's first law states that an object at rest will remain at rest, or an object moving with constant velocity will continue to move with the same velocity unless acted upon by an external force.
• Acceleration is the rate at which an object changes its velocity, measured as meters per second squared (m/s^2).
• Newton's third law states that every action has an equal and opposite reaction.
• Acceleration is the rate of change of velocity.
• Force is defined as mass times acceleration (F = m * a).
• Force is defined as mass times acceleration (F = m * a), where F is the magnitude of the force, m is the mass of the object, and a is the acceleration of the object.
• Mass is a measure of the amount of matter in an object, while weight is the gravitational pull on an object due to Earth's gravity.
• Mass is a measure of the amount of matter in an object, while weight is a measure of the gravitational pull on an object.
• Weight is the gravitational pull on an object due to Earth's gravity.
• The SI unit for force is newtons (N) and it can be calculated using the formula F = ma.
• An example of a vector quantity is displacement, while examples of scalar quantities include distance traveled and speed.
• The formula for calculating weight is W = mg, where W is the weight, m is the mass, and g is the gravitational constant (9.81 m/s^2).
• The first law states that if there are no forces acting on an object, it will remain at rest or continue moving with constant speed in a straight line.
• If there are no forces acting on an object, it will remain at rest or continue moving with constant speed in a straight line.
• Velocity is the rate of change of displacement, with respect of time measured in metres per second (m/s)
• When two objects are moving do they have the sane momentum , do they have the same speed?


  No they could have different masses
• When two objects have the same momentum do their velocities have a same direction ?

  Ye because momentum and velocity are both vectors
• acceleration is the change of distance with repect to time.
• Unit of force /newton is the force that causes a mass of one kilogram to accelerate by one meter per second per second
• Newton second law is the force acting on an object is directly proportional to the acceleration of the object
• Momentum: the quantity of motion of a moving body, measured as a product of its mass and velocity.
• The principle of conservation of momentum states that the total momentum of an object before an interaction is equal to the total momentum of the object after the interactio where there are no external forces
• Mass is the amount of matter in an object, measured in kilograms.
• Weight is the force of gravity acting on an object, measured in newtons (N)
• Mass is a scalar
• Weight is a vector
• Force is a vector quantity, meaning it has both a magnitude and a direction.
• Work is converted into kinetical energy by the work done formula: Work = Force x Distance
• Kinetic energy is energy due to motion
• Potential energy is stored
