False
The airplane had an increase of 100kph over a 2 hour period.
100 / 2 = 50.
so that would be 50 kph average acceleration.
False
False. Acceleration is the rate of change of velocity. Average velocity is the total displacement divided by the total time.
False. Average acceleration is calculated as the change in velocity divided by the time interval over which the change occurs, not from the slope of a velocity vs. time graph.
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.
False. Acceleration is a change of speed or direction over time.
False
False. Acceleration is the rate of change of velocity. Average velocity is the total displacement divided by the total time.
false because if you think of a paper airplane flying against the wind it will fall faster then the paper airplane flying with the wind
False. Average acceleration is calculated as the change in velocity divided by the time interval over which the change occurs, not from the slope of a velocity vs. time graph.
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
False, pterosaurs were flying reptiles.
False
False. A negative slope on a velocity vs. time graph indicates that the object is decelerating, not that it is not accelerating. Acceleration and deceleration are both forms of acceleration, but in opposite directions.
False. Acceleration is a change of speed or direction over time.
No, a plane flying against a jet stream will travel slower than a plane traveling with a jet stream. The jet stream is a high-altitude wind that can either boost or hinder an aircraft's speed depending on the direction of travel in relation to it. Flying with the jet stream provides a tailwind, increasing the aircraft's ground speed, while flying against it results in a headwind, reducing the ground speed.
