Kinematics
If Energy Is Not Added Or Removed From A System So That No External Work Is Done On The System What Happens To The Total Mechanical Energy Within That Closed System?
Remains Constant
Increases
Cycles Between High And Low Values
Decreases
In which situation would an object have zero acceleration?
When it starts moving from rest.
When it changes direction while maintaining its speed.
When it slows down while moving uphill.
When it travels at constant speed in a straight line.
What does the area underneath the curve of a velocity vs time graph indicate?
The force experienced by the object
The acceleration of the object
The impulse imparted to an object
The displacement of the object
¿Cuál sería el resultado más probable si una bola es lanzada hacia arriba con una velocidad inicial muy alta en un planeta con un campo gravitatorio mucho más fuerte que el de la Tierra?
Aumento significativo en el tiempo máximo
Ligero cambio en el ángulo óptimo para lograr el alcance máximo
Reducción marginal en aceleración debido al arrastre atmosférico
Incremento insignificante en la distancia máxima alcanzada
Which variable does the slope of a position vs. time graph represent?
Time
Displacement
Velocity
Acceleration
On a distance-time diagram for an object experiencing uniform circular motion, the steepness of the slope at any given point correlates most directly to which physical quantity?
Angular velocity around the circle
Direction change per unit time
Centripetal acceleration toward the center of the circle
Instantaneous speed along the tangent to the circle
As a ball thrown straight up reaches its highest point, what happens to its kinetic energy?
It transforms entirely into chemical energy.
It increases to a maximum value.
It decreases to zero.
It remains constant.

Which tool would you use to find out how much force is applied by an object when it collides with another object?
Thermocouple
Stopwatch
Force sensor
Speedometer
What does a flat line at a constant value of velocity on a time graph indicate about an object's motion in relation to acceleration and displacement?
The total displacement is zero since the velocity line is flat and parallel to the time axis.
There must be an external force acting on the object to maintain constant velocity.
The object is not accelerating but its displacement is continuously increasing at that velocity.
The object is experiencing negative acceleration since the line is flat even if positively valued.
Which type of potential energy is most relevant when discussing a roller coaster at the top of a hill?
Gravitational potential energy.
Elastic potential energy.
Electrical potential energy.
Magnetic potential energy.
