Unbalanced Forces
When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
Weight
- a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
a piece of metal known to weigh a definite amount and used 2. on scales to determine how heavy an object or quantity of a substance is.
non-contact force
The force which acts on an object without coming physically in contact with it is called non-contact force. The most familiar example of a non-contact force is weight. In contrast a contact force is a force applied to a body by another body that is in contact with it.
-
Gravity
the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
-
Falling
move from a higher to a lower level, typically rapidly and without control.
-
Base of Support
The base of support (BOS) refers to the area beneath an object or person that includes every point of contact that the object or person makes with the supporting surface. These points of contact may be body parts e.g. feet or hands, or they may include things like crutches or the chair a person is sitting in.
-
Newton
the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one metre per second per second, and is equivalent to 100,000 dynes.
Balanced Force
Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.
Fluid Friction
Fluid friction is the force that resists the movement of a solid object through a fluid (liquid or gas). Sky divers falling down through the sky experience a type of fluid friction called air resistance
Motion
- the action or process of moving or being moved.
- a formal proposal put to a legislature or committee.

Air Resistance
BSL Physics Glossary - air resistance - definition. Translation: Air resistance is a force that is caused by air. The force acts in the opposite direction to an object moving through the air. ... air resistance.
Force Arrows
In contrast, 10 Newton, downward is a complete description of the force acting upon an object; both the magnitude (10 Newton) and the direction (downward) are given. Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow.
-
resistance force
In physics, resistance force is the force which an effort force must overcome in order to do work on an object via a simple machine. Resistance force, like most other forces, is measured in newtons or in pounds-force.
Traction
the action of drawing or pulling something over a surface, especially a road or track.
Drag
pull (someone or something) along forcefully, roughly, or with difficulty.
