- Q3What happens to an already moving object if balanced forces are applied to it?It stays stationaryIt keeps moving at the same speed but in a different directionIt comes to a gentle stopIt keeps moving at the same speed in the same direction60s
- Q4What can we say about a stationary object?It must be made of heavy materialThere is no force applied to itThe forces applied to it are unbalancedThe forces applied to it are balanced
