Force
What is force?
strength or energy as an attribute of physical action or movement.
What is motion?
the action or process of moving or being moved.
What is velocity?
the speed of something in a given direction.
What is acceleration?
a vehicle's capacity to gain speed within a short time.
What is direction?
a course along which someone or something moves.
What is the unit of measure for force?
Newton
What is Newton's First Law of Motion?
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it
In a tug of war, when one team is pulling with a force of 100 N and the other 80 N, what is the net force?
20 N
What is Newton's 2nd Law of Motion?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
In the equation F = ma, what does m represent?
Mass
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction
What is the force that acts between two object in contact because of action-reaction?
Friction Force
The tendency for a stationary object to remain at rest, and for a moving object to continue at the same speed is called:
Inertia
