Force and Motion

A push or pull that can change the motion of an object.

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Forces that are not equal and can cause an object to accelerate or change direction.

The overall force acting on an object when all the individual forces are combined.

Add all the forces acting on an object, taking into account their direction.

Newton (N) is the unit used to measure force.

The change in position of an object over time.

The tendency of an object to resist changes in its state of motion.

A book resting on a table, where the force of gravity is balanced by the normal force of the table.

A soccer ball being kicked, where the force of the kick is greater than the friction holding it in place.
