If it continues at the same rate for another 3 seconds, what is its new velocity?, 12 m/s, 21 m/s, What is the correct sequence of motion for a jeepney that starts from rest, then moves at a steady speed, then stops?, Constant velocity → Acceleration → Deceleration, Acceleration → Constant velocity → Deceleration, A bicycle's motion has three phases. Which statement best describes these phases from a graph?, Increasing slope (speeding up), constant slope (steady speed), decreasing slope (slowing down)., Constant slope (steady speed) during the entire time., Comparing a tricycle and a bicycle, which conclusion is most accurate?, The tricycle is accelerating, while the bicycle has phases of speeding up, steady speed, and slowing down., Both vehicles are moving at a constant speed., A jeepney slows down from 12 m/s to 0 m/s in 4 seconds. What is the cause, and what is its acceleration?, A. The driver steps on the gas; acceleration is +3 m/s²., B. The driver steps on the brakes; acceleration is -3 m/s²., On a distance-time graph, what shape shows that an object is experiencing uniform acceleration?, A curved line that gets steeper., A straight diagonal line., As time increases on a distance-time graph for a tricycle, the distance traveled also increases. What does a constant rate of increase look like?, A curved line., A straight, diagonal line., If a jeepney's velocity-time graph shows a straight line sloping downward, what will most likely happen at t = 8 seconds?, The velocity will be lower than at t = 6 seconds., The velocity will be higher than at t = 6 seconds., Which evidence correctly links to the definition of acceleration to prove a tricycle is accelerating?, The tricycle had three wheels., The tricycle changed its velocity from 0 m/s to 8 m/s., Using the scientific definition, which objects are accelerating?, A speeding tricycle and a bicycle going around a curve., A parked jeepney and a basketball player standing still., For work to be done on an object, what must happen?, A force must cause the object to move in the direction of the force., A force is applied to the object, but it doesn't move., Marie pushed a box with 50 N of force, and it moved 3 meters. What information proves he did work?, The force applied and the distance moved., The box was heavy and made of wood., Which information is needed to calculate Marco's power output?, Force applied, distance moved, and time taken., The material the table was made of., Which student had the highest power output?, Lia (80 W), Des (70 W), Which objects have potential energy?, The child at the top of the swing, the ball at the top of the slide, and the child at the top of the seesaw., The boy running across the field., What evidence proves the child on the swing has potential energy at the highest point?, The swing chains are made of metal., The child is at the highest point and is not moving., If the marble is released from a greater starting height, what will happen to its speed at the end?, It will be faster because it starts with more potential energy., It will be the same because the track length is the same., In a roller coaster, what is the relationship between a marble's height and its speed?, As height decreases, speed tends to increase., As height increases, speed also increases., Why does the marble slow down as it moves from the bottom of a hill to the top of the next hill?, Kinetic energy is being transformed into potential energy., Potential energy is being transformed into kinetic energy., What happens to the speed at the bottom of a hill when the starting height is increased?, The speed at the bottom increases., The speed at the bottom decreases., If the starting height is lower, what is the effect on energy?, More potential energy is converted to more kinetic energy, resulting in a higher speed., More potential energy is converted Less potential energy is converted to less kinetic energy, resulting in a lower speed., What is the main energy change when water stored behind a dam is released?, Potential energy to kinetic energy., Kinetic energy to potential energy., What is the main purpose of the spinning turbine in a hydroelectric dam?, To store more water., To generate electricity., When stored water is released, what happens to its potential energy?, It is converted to kinetic energy., It is destroyed.
