Answer 1

1) Which example identifies a change in motion that produces acceleration
A speed skater moving at a constant speed on a straight track
A ball moving at a constant speed around a circular track
A particle moving iin a vacuum at constant velocity
A vehicle moving down the street at a steady speed

2)Objects is free fall near the surface of Earth experience
Constant speed
Constant Velocity
Constant acceleration
constant distance

3) Suppose you increase your walking speed from 1 m/s to 3m/s om a period of 1 s . What is your acceleraton
2m/s^2
5m/s^2
5m/s^2
3m/s^2

4)The slope of a speed time graph indicates
Direction
Acceleration
Velocity
speed

5) A train approaching a crossing changes speed from 25m/s to 10 m/s in 240 s. How can the trains acceleration be described
Trains acceleration is positive
The train is not accelerating
The train will come to rest in 6minutes
The train has a negitive acceleration

6) What is instantaneous acceleration
How fast a speed is changing at a specific instant.
How fast a velocity is changing at a specific instant
How fast a direction is changing at a specific instant
All of the above
