Which is NOT true of acceleration?
Acceleration of an object is zero if the forces acting on the object are balanced.
Acceleration is the greatest when change in velocity is the greatest for the same change in time.
An object is accelerating when it is at rest.
The steepest line on a velocity/time graph shows the fastest acceleration.
Which BEST describes the object's motion according to the graph?
The object is accelerating for the first 2 seconds, then is in constant motion for the next 5 seconds, and finally decelerates for the last second.
The object is moving at a constant speed for the first 2 seconds, then is at rest for the next 5 seconds, and moves fast back home in 1 second.
The object is moving away from home for the first 2 seconds, then moves at a velocity of 4 for the next 5 seconds, and finally returns home in 1 second.
The object travels 4 m in the first 2 seconds, then is in constant motion for the next 5 seconds, and finally decelerates for the last second.
When is the object moving the fastest?
O-A
A-B
B-C
Which BEST describes the object's motion according to the graph?
The object moves away from home in the first 2 seconds, is at rest for 3 seconds, then takes 2 seconds more to return home.
The object accelerates during the first 2 seconds, is at rest for 3 seconds, then decelerates for 2 seconds.
The object accelerates during the first 2 seconds, is at constant velocity of 40 m/s for 3 seconds, then takes 2 seconds to come to rest.

Remove the nail from within the coil.
Move the battery closer to the nail.
Increase the number of loops in the coil.
