Laws of motion

Cards (28)

  • Newton's first law of motion states that an object at rest will remain at rest, and an object in motion will continue moving with a constant velocity, unless acted upon by an external force.
  • For every action, there is an equal and opposite reaction.
  • Acceleration = Net Resultant Force / Mass
  • Force (N) = Acceleration (m/s^2) x Mass (kg)
  • Force is equal to the mass of an object multiplied by its acceleration.
  • Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.
  • The acceleration produced is directly proportional to the net resultant force acting on it and inversely proportional to its mass.
  • The acceleration produced by the net resultant force acting on a body depends directly on the magnitude of the force and inversely on its mass.
  • If two forces act simultaneously on a particle, then their effects are equivalent to the effect of a single force called the resultant or composite force.
  • When two forces act simultaneously on a particle, they produce a resultant force which acts along the line joining the points where the forces act.
  • Force = mass x acceleration
  • The resultant force on an object can be calculated using the vector sum method or the scalar product method.
  • Inertia is the tendency of an object to resist changes in its state of motion.
  • The resultant force on an object can be calculated using the vector sum of all forces acting on it.
  • Mass is a measure of how much matter an object contains, while weight is a measure of the gravitational pull on an object.
  • Inertia is the tendency of an object to resist changes in its state of motion or rest.
  • The equation F=ma can be used to calculate the magnitude of the resultant force required to produce a given acceleration or to determine the acceleration produced by a known force.
  • A force can be calculated using the formula F=ma, where F represents force, m represents mass, and a represents acceleration.
  • Inertia refers to the tendency of objects to resist changes in their state of motion or rest.
  • If two objects have different masses but are subjected to the same net resultant force, they will experience different accelerations.
  • An example of calculating force using the formula F=ma is provided.
  • If two objects have different masses, they will experience different accelerations when subjected to the same force.
  • An unbalanced force causes an object to change its speed, direction, or both.
  • A larger mass requires more force to produce the same acceleration as a smaller mass.
  • When a force acts on an object, it causes a change in momentum.
  • When a constant force acts on an object, the product of the force and time interval gives the impulse imparted to the object.
  • When two forces act simultaneously on a particle, they produce a resultant force that has both magnitude and direction.
  • A vector quantity has both magnitude (size) and direction.
