The force that opposes objects moving through the air

Air resistance

The force that opposes objects moving through the air. Air resistance. Air resistance is the push of air against a moving object that slows it down.

forces that are equal but in opposite directions

Forces that are equal but in opposite directions

Balanced force

Forces that are equal but in opposite directions. Balanced force. Balanced force occurs when two forces acting on an object cancel each other out, causing the object to stay still or move at a constant speed.

the push or pull exerted on an object

Force explained in an easy to understand way.

the motion of a falling object when the only force acting on it is gravity

The motion of a falling object when the only force acting on it is gravity

Free fall

The motion of a falling object when the only force acting on it is gravity. Free fall. Free fall is when an object is dropping and the only thing pulling it down is gravity.

the attractive force between all objects that have mass

Gravity explained in an easy to understand way.

forces acting on an object to cause a change in motion

Forces acting on an object to cause a change in motion

Unbalanced force

Forces acting on an object to cause a change in motion. Unbalanced force. An unbalanced force is when one side pushes or pulls more than the other, causing something to start moving, stop moving, or change direction.
