Newton's First Law Vocabulary

Force

• the force that opposes the motion of one surface as it moves across another surface

• the amount of matter in an object; measured in grams (g)

• a push or pull acting on an object, measured with a spring scale in Newton (N) units

• the path that an object is moving or facing

Friction

• the force of attraction between all objects that is due to their masses

• the path that an object is moving or facing

• the energy of motion

• the force that opposes the motion of one surface as it moves across another surface

Unbalanced Force

• forces on an object that do not change the movement of the object; net force is zero

• forces on an object that cause change in the motion of the object; net force is not zero

• the force of attraction between all objects that is due to their masses

• the resistance of an object to any change in its motion

Inertia

• a push or pull acting on an object, measured with a spring scale in Newton (N) units

• how far apart two objects are

• the speed of an object in a given direction

• the resistance of an object to any change in its motion

Balanced Force

• forces on an object that do not change the movement of the object; net force is zero

• a change in an object's speed or direction; example: if a car is turning or speeding up

• forces on an object that cause change in the motion of the object; net force is not zero

• the stored energy an object has because of its position or shape

Gravity

• a force that works against an object's motion as it passes through air

• the stored energy an object has because of its position or shape

• the path that an object is moving or facing

• the force of attraction between all objects that is due to their masses
