1. Найдите все придаточные предложения, определите их тип. a) Newton’s 1st law of motion states that the velocity of an object will not change unless a resultant force acts on it. b) The fact is that the more force you have acting on a certain mass, the more acceleration you get. c) As the wing moves through the air, it pushes down on the air (and changes its direction). d) If a collision is inelastic it means that some of the kinetic energy is converted into other forms during the collision. e) Remember that acceleration is equal to the rate of change of velocity, so if mass is constant then this formula gives you that mechanics favourite, F = m × a.
2. Из неполных обстоятельственных придаточных предложений сделайте полные. a) Force fields can be represented as vectors, showing the direction of the force they would exert on an object when placed in that field. b) Although similar, gravitational and electric fields are not the same. c) We could measure the distance between two images of the tennis ball if necessary. d) When pushed and then released the stable object tended to return to its original position. e) Each drop falls in a different position, forming pictures and words on the paper as required.
