' Forces and Motion Study Guide Position: the location of an object Reference Point: any object that is not moving and can be used to describe the position of another object Distance: the length of a line between two points Motion: a change in an object’s position Direction: the path that a moving object follows Speed: a measure of how far an object moves in a certain amount of time; Distance / Time Constant Speed Increasing Speed Decreasing Speed Force: a push or pull on an object Objects move in the direction of the applied force A force can change the direction of an object’s motion and the speed. The greater the force, the greater the motion. The greater the mass, the less the motion. Objects that weigh less can move faster. Mass: how much matter makes up an object Matter: anything that has mass and takes up space Gravity: a force that pulls objects toward each other The more mass an object has, the greater its pull of gravity The closer two objects, the stronger the pull of gravity. Friction: a force that acts against motion; causes objects to move slower and eventually stop moving
