• Gravitational effects

2
Lesson 1 Vocabulary

• A push or pull that causes an object to move,
  stop, or change direction
• The use of force to move an object through a
  distance
• The pulling force between all objects the force
  that causes objects to fall toward Earth

Lesson 1 Vocabulary
weight

• A measure of the downward force of gravity on an
  object
• A tool used to measure
• weight of an object according to the
  pull of gravity
• The change in an objects position
• The measure of speed and direction

Spring scale
motion
velocity

Lesson 1 Vocabulary

• The measure of the distance an object moves in a
  set amount of time like 65 miles per hour
• A change in velocity (speed or direction
• The tendency of an object to resist a change in
  motion
• The force from 2 or more objects rubbing against
  each other 2 hands rubbing feet rubbing on
  carpet

speed
acceleration
inertia
friction

Lesson 1 Vocabulary

• The unit to measure force
• Force exerted by a body moving through air
  because of friction like sky diving
• A tool that uses weights to determine the mass of
  an object

newton
