# Collisions and Forces Science Games

3 games

In this series of games, your students will learn that when objects collide, the contact forces transfer energy so as to change the objects’ motions. Collisions and Forces learning objective — based on NGSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research.

Scroll down for a preview of this learning objective’s games and the concepts.

## Concepts Covered

A force is a push or pull on an object. A force has both a strength and a direction. A contact force is a force that occurs when objects are in direct contact with each other. Friction is a contact force that opposes the motion of an object. A non-contact force is a force that can act on an object over a distance. The magnetic force is a non-contact force between magnetic objects.

Motion is the change in the position of an object. Moving objects contain energy. When objects collide, energy is transferred from one object to the other, changing their motion. When an object slides relative to another, the frictional forces between them transfer the energy of motion into heat energy, causing the object to slow down.

A magnetic object has both a north pole and a south pole. Similar magnetic poles will repel each other. Opposite magnetic poles will attract each other.

When a force acts on an object, it transfers energy to the object that affects its motion. The electric force is a non-contact force between electrically charged objects. Objects with the same electric charge will repel each other. Objects with opposite electric charges will attract each other. On a microscopic level, contact forces between objects are the result of electromagnetic forces.
