(16 cards)
Define speed
change in distance
Define Resultant Vector
The single vector which has the same effect as all the original vectors acting together
Define distance
The length of the path traveled
Define displacement
Change in position
State Newtons 3rd Law
When object A exerts a force on object B, Object B exerts an equal and opposite force on object A
Newtons 1st law
An object in motion or at rest will remain in motion or rest until acted apon by a net external force
Acceleration
Rate of change of velocity
How to get a more accurate answer
Repeat the experiment more than once and use the average result
Scalars
STD ME
Speed, Time, Distance, Mass, Energy
Vectors
FAW DV
Force, Acceleration, Weight, Displacement, Velocity
Velocity
Change in displacement
Newtons 2nd Law
When a Net force is applied to an object, the object will accelerate in the direction of the force.
Acceleration is directly proportional to the Net force and inversely proportional to the Mass
Define frictional force
The force that opposes the direction of an object on a surface
Normal Force
The force that acts perpendicular to the surface of the object
Define Equilibrium
The state at which opposing forces are balanced and equal
Free fall
Movement due to the force of gravity only
