Speed Exam Review

A cruise ship is travels northeast at 23 miles/hour. This is the cruise ships __________.

• Velocity

• Acceleration

• motion

• average speed

​ (a)   is any change in the position or location of an object. A ​ (b)   is a point in space used to compare the position of things. ​ (c)   is how far an object travels as it moves from one position to another (total).

• Motion
• reference point
• Distance
• Speed
• Density

​ (a)   is how far an object is from the starting point, regardless of the path it took to get there. ​ ​ (b)   is a description of how fast an object is moving = distance/time. ​ (c)   is a description of how fast velocity is changing ex. speed up, slow down, or change direction.

• Displacement
• Density
• Motion
• Speed
• Acceleration

_____________ is a description of how fast an object is moving and in what direction.

• Motion

• Velocity

• Speed

• Density

The equation for speed is ________________________.

• distance x time

• distance - time

• distance / time

• distance + time

Answer explanation

Using the speed triangle, finish the equation. Distance = ________________________.

• speed x time

• speed/time

• speed + time

• speed - time

All of these are considered acceleration EXCEPT-

• increase in speed

• decrease in speed

• change in direction

• not moving

If a car travels 328m in 15 seconds, how fast is it going? (draw your speed triangle)

Mathematical Equivalence

ON

A whale swims at a constant speed of 8.0 m/s for 17s. Calculate the distance travelled by the whale. (Use your speed triangle)

Mathematical Equivalence

OFF

A beetle travels at a speed of 0.09 m/s, it travels a distance of 1.08 m before it is caught in a jar. Calculate the time taken for the beetle to run. (use speed triangle)
