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
