Air resistance explained in an easy to understand way.
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.
Balanced force explained in an easy to understand way.
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.
Force explained in an easy to understand way.
Force
The push or pull exerted on an object. Force. It's what makes things move or stop moving.
Free fall explained in an easy to understand way.
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.
Gravity explained in an easy to understand way.
Gravity
The attractive force between all objects that have mass. Gravity. Gravity is a force that pulls objects toward each other, like how the Earth pulls us down so we stay on the ground.
Unbalanced force explained in an easy to understand way.
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.
Weight explained in an easy to understand way.
Weight
Measure of the force of gravity on an object. Weight. Weight is how heavy something is because of gravity pulling it down.
