WorksheetsUnit 6 Vocabulary- Force & Motion
Total questions: 15
Worksheet time: 9mins
a push or a pull exerted on an object that may change the motion or shape of the object; force has strength and direction
force
motion
acceleration
inertia
the rate at which someone or something is able to move or operate
Speed
motion
acceleration
inertia
the action or process of moving or being moved.
force
motion
acceleration
inertia
the tendency of an object to resist changes in motion
force
motion
acceleration
inertia
the rate of change of velocity per unit of time
force
motion
acceleration
inertia
a place or object used for comparison to determine if something is in motion
reference point
speed
radar device
velocity
electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances
reference point
speed
radar device
velocity
the total distance traveled by the object in a particular time interval.
speed
average speed
net force
gravity
the combined effect (the sum) of the real forces acting on the object
speed
average speed
net force
gravity
a force that resists motion between a moving object and the air around it
force
air resistance
friction
motion
Match the following
unless acted on by an unbalanced force, an object at rest stays at rest and an object in motion stays in motion at a constant velocity; unbalanced forces cause an object to accelerate (change direction or speed).
1st Law of Motion
greater net force causes a greater acceleration for a given mass. For two objects with the same net force, the object with the greater mass accelerates less than the object with less mass.
2nd Law of Motion
states that when one object applies a force to a second object, the second object applies an equal and opposite force to the first object.
3rd Law of Motion
a force that opposes motion between two materials that are in contact
force
air resistance
friction
motion
is the international unit of measure for force. It is equal to the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.
mass
newton
kilogram
energy
the speed of something in a given direction.
reference point
speed
radar device
velocity
a force of attraction between objects that is due to their masses and that decreases as the distance between the objects increases
reference point
speed
velocity
gravity
