3. [PDF] Newton's First Law - Center Grove
An object will speed up, slow down, or turn only if something is pushing or pulling on it. A force is a push or a pull. Examples of forces are shown in.
4. Newton's First Law and the "State of Motion" - The Physics Classroom
A 4.0-kg object is moving across a friction-free surface with a constant velocity of 2 m/s. Which one of the following horizontal forces is necessary to ...
An object's state of motion is defined by how fast it is moving and in what direction. Speed and direction of motion information (when combined, velocity information) is what defines an object's state of motion. Newton's laws of motion explain how forces - balanced and unbalanced - effect (or don't effect) an object's state of motion.

... surface upon which the object is resting. ... Dynamics is the study of the causes of motion, namely forces. A force is a push or a pull experienced between two ...
What happens when you hit the brakes in a car that makes you come to a stop, or what happens to the parachutist as she jumps out of the plane that makes her fall faster and faster -- this is the study of dynamics. Dynamics is the study of the causes of the different motions: uniform and non-uniform.

14. Science Focus Lesson SC.5.P.13.1 Forces - ppt video online download
Forces cause objects to start moving, stop moving, change speed or direction. A push or a pull is necessary to start an object in motion.
SC. 5.P.13.1 Benchmark: Identify familiar forces that cause objects to move, such as pushes or pulls, including gravity acting on falling objects. Essential Question: How is the motion of an object affected by the forces acting upon the object? Vocabulary: force magnetic force gravity friction Force- a push or a pull Gravity-a natural force that pulls objects towards each other Magnetic force- a force that pulls magnetic materials across a distance Friction- a force between two surfaces rubbing against each other. Friction works against the motion of an object.
