What would cause an object moving at a constant speed to increase speed?
O The increase in speed is caused by a balanced force.
O The increase in speed is caused by an unbalanced force.
O The increase in speed is caused by a change in direction.
O The increase in speed is caused by a frictional force.
The increase in speed is caused by an unbalanced force.
