|Forces are a
|push or a pull on an object
|Newton's First Law
|an object in motion remains in motion unless acted upon by an unbalanced force (forces are balanced)
|Newton's Second Law
|force is directly related to an object's mass and acceleration (forces are unbalanced)
|Newton's Third Law
|For every action there is an equal and opposite reaction
|Example of Newton's First Law
|A car going a constant speed
|Example of Newton's Second Law
|A car accelerating
|when an object speeds up, slows down, or changes direction
|Example of Newton's Third Law
|Gases of rocket push ground down and ground pushes gases of rocket up.
|A toy car has a 5 N applied in the forward direction as well as a frictional force of 2 N. What is the net force acting on the car?
|What is the acceleration of a 10 kg object that has a force of 20 N?
|If a ball is hit with 4x the force, it will result in _______ the acceleration?
|If an object is accelerating its net force is?
|Not 0 N
|What is the relationship between mass and acceleration?
|inverse or indirect
|Weight is ______.
|force of gravity on an object
|A 0.02 kg piece of gum hits a paper projectile with a 1 N force. If the projectile is now traveling at a constant velocity, what is its acceleration
|If a 100 kg female traveled to the moon where gravity is 1/6th of the Earth's gravity (g of moon= 1.63 m/s^2), how much would she weigh?
|If a ball has a mass of 30 N on the Earth, what is it's mass on the moon (g of moon = 1.63 m/s^2)
|What is the unit of force?
|What is the unit of mass?
|What is the unit of acceleration?
|What is the unit of speed?
|What is another way to write the unit of a Newton?
|What do call the force that is perpendicular to the surface?
|The opposite of the thrust force on an airplane is the _____.
|The opposite of the weight force on an airplane is the _____.
|True or False: A force is any interaction that changes and object's motion.
|True or False: A force is necessary to continue an object's motion.
