Objects in Motion

An astronaut kicks a soccer ball in outer space at a location far from significant influences of gravity and air resistance. The soccer ball will _________.

• continue in motion with the same speed and direction

• eventually stop as its inertia slowly becomes used up

• eventually stop since all objects ultimately "lose their steam"

• either a, b, or c -- depending on whether the astronaut continues to kick it

when an object changes its position relative to a reference point.(moves)

• Motion

• Speed

• Acceleration

• Position

A place or object used for comparison to determine if something is in motion

• Velocity

• Acceration

• Position

• Reference Point

is the distance and direction of an object's change in position from the starting point.

• Distance

• Displacement

• Velocity

• Acceration

the speed and direction of an objects motionh

• speed

• velocity

• position

When two or more forces act on an object at the same time; combined forces.

• velocity

• displacement

• inertia

• net force
