Motion of objects Vocab

balanced forces

• Equal forces act on an object in opposite directions; when the net force on an object is 0 N

• Equal forces act on an object in same directions; when the net force on an object is 0 N

Unbalanced forces

• two or more forces that are equal and opposite of one another; can cause change in motion; when net force on an object is not 0 N.

• two or more forces that are not equal and opposite of one another; can cause change in motion; when net force on an object is not 0 N.

Net Force

• the rate of change of velocity per unit of time; speeding up

• The combination of all forces acting on an object

Speed

• The distance an object travels per unit of time

• the rate of change of velocity per unit of time; speeding up

constant speed

• the rate of change of position in which the same distance is traveled each second

• the path that a moving object follows

Acceleration

• the rate of change of velocity per unit of time; speeding up

• An object's change in position relative to a reference point.

negative acceleration

• slowing down

• the path that a moving object follows

Displacement

• The combination of all forces acting on an object

• Distance and direction of an object's change in position from the starting point.

direction

• the rate of change of velocity per unit of time; speeding up

• the path that a moving object follows

Motion

• The distance an object travels per unit of time

• An object's change in position relative to a reference point.
