- Q6If an object is moving downward, and the forces shown begin acting on it, what will happen to the motion of the object?It's speed will increase downwardIt's speed will decrease, but it will keep moving downwardIt will start moving upwardsIt's speed will not change30s
- Q7If an object is moving to the right, and the forces shown begin acting on the object, what will be true about the object's motion?It will continue moving at a constant speed to the right.It will slow down but will keep moving right.It will accelerate right30s
- Q8If an object is moving right, and the forces shown begin acting on it, what will happen to the object's motion?The object will slow down, but keep moving rightNothing will happen to the object's motion, it will keep moving right at a constant speed.The object will speed up to the rightThe object will immediately turn around and start moving left30s
- Q9If an object is moving left, and the forces shown begin acting on the object, what will happen to the motion of the object?The object will speed up to the left.The object will continue moving left, but will slow down.The object will immediately turn around and start moving right.Nothing will happen to the object's motion. It will continue moving left at a constant speed.30s
- Q10An object is at rest. The forces shown start acting on it. What will happen to the object's motion?The object will speed up to the leftNothing will happen, the object will stay at rest.The object will move at a constant rate to the left, but will not speed up after it gets moving.The object will speed up to the right.30s
- Q11An object is traveling upwards, and the forces shown are acting on it. What can be said about the object's motion?It is moving upwards with a constant speed.It is moving upwards, and is speeding upIt is moving upwards, but is slowing down.30s
- Q12An object is moving to the right with the forces shown being acted on it. What can be said about the motion of the object?It is moving right at a constant speed.It is moving right but is slowing down.It is moving right and is speeding up.30s
