- Q1The combination of all the forces acting on an object.Net force30s7.P.1.2
- Q2When equal forces are acting on an object in opposite directions. The net force is zero. The object's motion does not change; it remains at rest or at constant speed.Balanced Forces30s7.P.1.2
- Q3When the net force acting on an object is not zero resulting in a change in motion. Causes an object to start moving, stop moving or change direction.Unbalanced forces30s7.P.1.2
- Q4The unit for force in the SI system.Newton30s7.P.1.1
- Q5An object that is thrown.Projectile30s7.P.1.1
- Q6The Product of an object's mass and velocity.Momentum30s7.P.1.1
- Q7States that when there are no outside forces the total momentum of objects that interact does not change.Law of Conservation of Momentum30s7.P.1.1
- Q8The fluid friction experienced by objects moving through the air.Air resistance30s7.P.1.1
- Q9The greatest velocity a falling object can achieve.Terminal Velocity30s7.P.1.1
- Q10The motion of an object when the only force acting on it is gravity.Free fall30s7.P.1.1
- Q11Overall rate of speed at which an object moves.Average speed30s7.P.1.1
- Q12The speed of an object in one instant of time.Instantaneous speed30s7.P.1.1
