If forces of the same strength are acting on an object in such a way that the object does NOT move, the object is said to be
in equilibrium
doing work
in free fall
dynamic
Which statement about the movement of an object with zero acceleration is true?
The object must be at rest.
The object must be slowing down.
The object may be speeding up.
The object may be in motion.
A push or pull best describes the term
(a)
Magnetic force is strongest at a magnet's
(a)
Acceleration due to gravity is approximately 9.8m/s^2. This suggests that ALL objects, no matter their mass, will fall freely from the same point above the Earth's surface at the SAME acceleration.
True
False
If the NORTH side of a magnet comes in contact with the NORTH side of another magnet, will the magnets attract or repel?
(a)
If the SOUTH side of a magnet comes in contact with the NORTH side of another magnet, will the magnets attract or repel?
(a)
A 200 N box is sitting on a table. Therefore, the table must be exerting a force of (a) N in order to hold the box in place.
What force opposes motion and can slow or stop a rolling object?
(a)
The object in the graph represented by the line is moving with
increasing acceleration
decreasing acceleration
increasing speed
constant speed
The use of lubricants such as oil in a car's engine helps to reduce the force of (a) , resulting in less heat.
According to the graph, during which interval was the object accelerating/changing speed?
AB
BC
CD
DE
The force of gravity between two objects is greatest when their masses are large and the objects are close together.
True
False
A rocket engine thrusts the rocket into space because every action produces an equal and opposite reaction. This is an example of Newton's
1st law
2nd law
3rd law
"A body at rest tends to remain at rest, and a body in
motion tends to remain in motion, unless acted upon
by an unbalanced force" is a statement describing (check all that apply)
Newton's 1st law
the law of inertia
Newton's 2nd law
the law of mass
What equation can be used to find the speed of a moving object if given the distance the object travels and the amount of time it took to travel said distance?
speed = time/distance
speed = distance x time
speed = distance/time
speed = time x distance
Magnetism is caused by the spinning of
protons
neutrons
kryptons
electrons
