Question

1. a butterfly flutters at a rate of 18 feet per minute. this is an example of
2. identify each scenario in the table below as speed, velocity, or acceleration.

after a skydiver deploys his parachute, his rate of speed decreases. light travels at 299,792,458 meters per second. water travels down in a waterfall at a rate of 15 feet per second.

Explanation:

Step1: Define speed, velocity, acceleration

Speed is a scalar quantity representing how fast an object is moving. Velocity is a vector quantity with both speed and direction. Acceleration is the rate of change of velocity.

Step2: Analyze butterfly fluttering

The butterfly's rate of 18 feet per minute only gives how fast it moves, no direction, so it's speed.

Step3: Analyze skydiver scenario

The skydiver's rate of speed decreases. Since acceleration is change in velocity (here change in speed), it's acceleration.

Step4: Analyze light - travel scenario

Light travels at 299,792,458 meters per second. This only gives how fast light moves, no direction, so it's speed.

Step5: Analyze waterfall scenario

Water travels down in a waterfall at a rate of 15 feet per second. This only gives how fast the water moves, no direction, so it's speed.

Answer:

1. speed
2. acceleration, speed, speed
