forces and motion

an object's change in position relative to a reference point

• speed

• reference point

• motion

a force that opposes motion between two surfaces that are in contact

• gravity

• friction

• mass

When two or more equal forces act upon an object, resulting in no motion.

• friction

• balanced force

• unbalanced force

• inertia

What type of force causes a reaction or movement?

• balanced force

• unbalanced force

What is the line on this graph showing?

• moving away from starting point at a constant speed

• moving back towards the starting point at a constant speed

• acceleration (getting faster)

• deceleration (getting slower)

An airplane is travelling North through the sky at a constant speed when turbulence causes it to take a different route, changing its direction. Explain the forces at work on this plane.

• Unbalanced, because the plane is moving forward, not backwards
• Unbalanced, because the speed is constant and there is a change in direction
• Balanced, because the plane is not falling to a lower altitude
• Unbalanced, because the plane is in motion
