True/False: If the average speed of an object is zero, then its average velocity must be zero, but t its average velocity is zero, its average speed is not necessanily zero False An object is dropped from rest into seconds. How much deeper is the second pit, compared to the first pt? a pit, and accelerates due to gravity at roughly 10 m/s2. it hits the ground in 5 seconds A rock is then dropped from rest into a second...

True or false: 1) If a net force acts on an object, the object's speed will change. 2) The net force which acts on an object which remains at rest is zero. 3) An object's velocity will change if a net force acts on the object. 4) If a net force acts on an object, the object's velocity will change. 5) If an object's speed does not change, no net force is acting on the object. Please write why they...

An object is moving forward with a constant velocity. Which statement about this object MUST be true? A. No forces are acting on the object. B. The net force on the object is in the forward direction. C. The acceleration of the object is in the forward direction. D. The net force on the object is zero.

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...

26. Can an object be moving at a constant speed, but still have acceleration? A. Yes, because the object is gaining speed at a constant rate. B. Yes, because the object is changing direction. C. No, if it's moving at a constant speed it is not accelerating. D. No, because the object will eventually slow down. 27.In the quantum theory of hydrogen, as an electron drops to lower EPE orbit, it emits a photon with missing energy equal to A....
