🗑
Scalar   show
🗑
show This changes the magnitude and may reverse the direction  
🗑
show Product of the vectors' magnitudes and the cosine of the angle between them.  
🗑
Note About Multiplying Two Vectors Using The Dot Product   show
🗑
Cross Product   show
🗑
show This results in a vector quantity  
🗑
show Vector rep. of change in position  
🗑
Distance   show
🗑
Velocity   show
🗑
Average Velocity   show
🗑
show Limit of the change in displacement over time as the change in time approaches zero.  
🗑
Instantaneous Speed   show
🗑
Force   show
🗑
show Attractive force between two objects as a result of their masses  
🗑
Friction   show
🗑
show Friction between two objects that are not in motion relative to one another.  
🗑
show Friction between two objects that are in motion relative to each other  
🗑
Coefficient of friction   show
🗑
Mass   show
🗑
show Force experienced by a given mass due to grav. accel to Earth  
🗑
Acceleration   show
🗑
show An object will remain at rest or move with a constant velocity if there is not net force on the object  
🗑
Newton's Second Law   show
🗑
show Any two objects interacting with one another experience equal and opp. forces as a result of their interaction.  
🗑
show Free fall and motion in which vel. and accel. vectors are parallel or antiparallel  
🗑
Projectile Motion   show
🗑
Inclined Plane   show
🗑
Circular Motion   show
🗑
