```Force, Motion and Energy Vocabulary
Term
Definition
acceleration
The change in an object’s speed or direction
(velocity) over time.
f=ma
The formula for finding force (N) by using
mass (g) times acceleration (m/sec2).
force
A push or pull.
Example
Traveling North
at 50 m/sec2
Pull
Push
friction
The force that resists the motion of two
surfaces that are touching.
gravity
The force of attraction between two objects.
inertia
An object’s tendency to resist changing its
motion.
motion
A change in position.
net force
The total amount of force acting on an
object.
5N, right net force
20N
Newton
normal force
s=d/t
speed
velocity
weight
The SI unit of force. Measured with a
spring scale.
15N
N
The force equal and opposite to gravity
The formula for finding speed.
Speed (m/sec) = distance (m) / time (sec)
The distance traveled by an object in an
amount of time.
Speed with a direction. Velocity has a unit
of m/sec + direction.
The measure of the gravitational force of
gravity on an object.
Measured in Newtons or grams
with a spring scale
