As the rate at which an object’s speed or direction changes What does the coefficient of friction represent? The ratio of the frictional force to the normal force between two surfaces; calculated as Coefficient of Friction = Frictional Force divided by Normal Reaction Force What is force? A push or pull; determined by Force = Mass X Acceleration What is frictional force? The resistance force between two surfaces that opposes their relative motion 2 What is the normal reaction force? The force exerted by gravity on an object when it is being pulled across a surface What is the SI unit used to measure force? Newton What does Newton's First Law of Motion state? An object will continue its current state of motion or rest unless acted upon by an external force What does Newton's Second Law of Motion describe? The relationship between the sum of forces acting on an object and its acceleration, expressed as Force = Mass X Acceleration
