JEOPARDY Force and motion
Force Motion 2 Motion 2 Newton’s Laws Newton’s Laws of Motion of Motion Newton’s Laws Newton’s Laws of Motion 2 of Motion
Category the cause of acceleration, or change in an object’s velocity.
Category Force
Category the total of all forces acting on an object
Category Net force
Category A force that does not change motion
Category Balanced force
Category The unit Force is measured in.
Category Newtons (N)
Category What unit is acceleration written in
Category m/s2
Category The formula to find acceleration
Category final speed – initial speed/time Or force/mass
Category The formula to find speed.
Category distance/time
Category the tendency of an object to resist a change in motion.
Category inertia
Category depends on the masses of the objects and the distance between them.
Category Gravitational force
Category force that resists motion between surfaces that are in contact.
Category friction
Category cause a change in motion
Category unbalanced force
Category force exerted between two objects that are not touching.
Category long-range force
Category a push or a pull
Category force
Category force exerted when two objects are touching each other.
Category Contact force
Category the speed traveled at an instant time.
Category Instantaneous speed
Category attraction between two particles of matter due to their mass
Category gravity
Category The greater the mass, the greater this is
Category inertia
Category States that when an unbalanced force is applied to an object the object accelerates. Acceleration = force/mass Force = mass x acceleration
Category Newton’s Second Law of Motion
Category occurs between surfaces that are sliding
Category Sliding friction
occurs between surfaces that are not sliding Category 4 500
Static friction Category 4 500
Category states that for every force there is an equal and opposite force.
Category Newton’s Third Law of Motion
Category For every action there is an equal and opposite
Category reaction
Category the motion of a body when only the force of gravity is acting on it.
Category Free fall
Category a measure of how much matter an object contains.
Category mass
Category the maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to the force due to gravity
Category Terminal velocity
