Show answer
If the forces on an object are balanced, the object will not change the way it is moving. If stationary, it remains at rest. If moving, it continues at constant speed in a straight line.
Also accept: The object remains at rest if stationary or moves at constant speed if already moving.
Common mistakes: The object stops moving

B2 · 1 mark · 1 mark for saying the object continues at constant speed in a straight line (if moving)
Worked solution
If an object is at rest and the forces are balanced, it stays at rest. If it is moving, it continues at the same speed and in the same direction.
