That one test on force and friction that is bad?
Flashcards do conjunto (10)
- 1Describe the difference between balanced and unbalanced forces.Unbalanced forces cause motion or a change in the state of motion in an object. Balanced forces do not cause a change in an objects state of motion.
- 256300/223150
- 3Does the inertia of an object change as it's velocity does?No inertia is not affected by velocity
- 4What is newtons 1st law of motion.An object in moving stays at a constant velocity unless an unbalanced force acts upon it.
- 5How do airbags assist in an accident?It keeps you from banging your head on the dashboard as it inflates then deflates.
- 6How does friction increase when a larger force pushes to surfaces togeather.As the surfaces get closer the number of static friction increases.
- 7What are the 4 types of friction that we studied in class that one event.Applied- The Force applied by one object onto another. Air resistance- The force applied on an object moving through the air. Normal- The force exerted on a resting stable object. Tension- The force transmitted by two objects pulling on each other.
- 8What is newtons second law of motion?the acceleration of an object is dependent upon two variables - the applied acting upon the object and the mass of the object.
- 9Formula for acceleration.f=m X a
- 10The formula for net force.A= Force over Mass
