Science Fusion Unit 8 Forces and Motion

Position is

• a change in postion

• the location of an object in relation to a nearby object or place

• the background

• the speed of an object of an object in a particular direction

Motion is

• The change in position

• The location of an object in relation to a nearby object or place

• The background

• How fast or slow something is moving

The reference point is the second object or place when talking about the position of an object.

• True

• False

The frame of reference is the second object or place when talking about the position of an object.

• True

• False

Speed is

• The speed of an object in a particular direction

• The change in position

• The background

• How fast or slow an object moves

Velocity is

• The background

• How fast or slow something is moving

• The speed of an object in a particular direction

• Walking toward the east

You calculate speed by dividing how far an object goes by the time it takes to get there.

• True

• False

Force is

• The speed of an object in a particular direction

• A push or pull

• How fast or slow something moves

• Any change in velocity

Gravity is

• The change in position

• A force that acts directly against the direction of motion

• A force that pushes objects up into the sky

• A force that pulls objects down to Earth

Friction is

• A force that acts directly against the direction of motion.

• A force that pulls objects down to Earth.

• A force that allows objects to slide easily.

• A force that pushes object towards the sky.
