The equation for velocity is__________

What is v=d/t?

100

The equation for acceleration is______

What is a=v/t

200
True/False: The rate at which distance is covered is called speed.
True s = d/t
200
True/False: Velocity is different from speed in that velocity is speed in a given direction.
True Velocity is a vector so it needs a magnitude and a direction. Velocity = speed + directions
200
True/False: The rate at which velocity changes with time is called acceleration.
True Acceleration is how quickly our velocity is changing. You find it by finding the slope on the Velocity-Time graph.
200
True/ False: Even though a car is slowing down, it is still accelerating.
TRUE. Any change in velocity is caused by acceleration. Slowing down, speeding up, or changing direction!

The equation for force is_______

What is F=m*a?

A rabbit is hopping uphill with a positive velocity while having a negative acceleration due to gravity. Describe the motion of the bunny in terms of speed. (speeding up or slowing down)
The bunny is slowing down. -a and +V = slowing down When the direction of velocity and acceleration are opposite, it slows down!!!

When you look at the speedometer in a moving car, you can see the car’s _____. (A) instantaneous speed. (B) average speed (C) average acceleration (D) instantaneous acceleration (E) average distance traveled (F) instantaneous position
A. Instantaneous Speed (how fast it's going at that moment)

If a swimmer has to swim 5 laps of the pool (to the end and back), with one length of the pool being 50 meters, what is the swimmer’s distance and displacement? (A) 250m, 250 m(B) 500m, 500m (C) 500 m, 0m(D) 500 m, 250m

(C) Distance:500 m (total distance swam), Displacement: 0m (difference between where they started and where they ended . . . they started and ended in same spot so no difference)

What does the slope of a position vs. time graph tell us? What is the SI Units for the slope of the position vs. time graph?
The slope shows velocity. The SI unit is m/s.

What does the slope of a velocity vs. time graph tell us? What is the SI unit for the slope of a velocity vs. time graph?
The slope of a velocity vs. time graph shows us Acceleration. The SI unit is m/s^2 (meters per second squared)

In baseball, a home run means the batter has hit the baseball into the stands, beyond the baseball field. Compare the force of the batter when bunting the ball into the in-field versus hitting a grand slam.

What is The force is much less when bunting into the in-field.
