1

A magician pulls out the tablecloth from under the dishes and they do not move.

1

If the cart’s wheel hits a large rock, causing the cart to suddenly stop. Which of the following is likely to happen as a result of Newton’s first law of motion?

1

What is the force?

1

What was the ball average speed during the time represented in the graph?
HINT; Divide rise/run Distance/time

1

What was the average speed of the toy car during the two trials to the nearest tenth of m/s?

HINT: Add all distances add all times then divide distance /time. then round your number

1

Which cart will result in the greatest change in speed?

1

What was the average speed in the first 40 seconds?
HINT; Divide rise/run Distance/time

1

A bus travels 20 km in 30 min. What is the average speed of the bus?
HINT: change your units from minutes to hours by dividing time by 60. then calculate speed. S=d/t

1

Based on the data in the table, which object experienced the greatest force?
HINT: use F=ma triangle; Calculate the force for each object

1

A block is pulled 0.5 m to the right in 4.67 s.
What is the average speed to the nearest hundredth of m/s?
Hint: Remember the rules of rounding.

Tides - Effects of the Moon on Earth
Each day, the ocean water rises and falls at different times. This movement of water is known as a tide. A tide is a change in water level at the shoreline. Tides are caused by the pull of gravity between Earth and the Moon and Earth and the Sun. During each 24-hour period, most beaches around the world will have two high and two low tides.
The Moon’s gravity has a powerful effect on Earths waters. In fact, it is far more powerful than the Suns because the Moon is closer to Earth than the Sun. The Moon pulls the water toward itself.
When the gravitational force of the Sun combines with the gravitational force from the moon it can increase a high tide by making it rise higher than normal. This will happen when the Moon is either in its new moon or full moon phase.
Each month most locations on earth experience 2 spring tides and 2 Neap tides.

Spring Tides: When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low.
Neap Tides: During First and last quarter the sun and moon work at right angles, causing the bulges to cancel each other.The result is a smaller difference between high and low tides and is known as a neap tide.
  • Neap tides are especially weak tides.

Match the month to the correct picture and three descriptions

  • In the Northern Hemisphere winter is occurring on the southern hemisphere summer is occurring
  • In the Northern Hemisphere Spring is occurring on the southern hemisphere fall is occurring
  • In the Northern Hemisphere summer is occurring on the southern hemisphere winter is occurring
  • In the Northern Hemisphere fall is occurring on the southern hemisphere spring is occurring
  • March
  • December
  • September
  • June
1

Match the month to the correct picture and three descriptions

  • The southern hemisphere has the warmest temperature and the sun is shining directly.
  • The sun is shining equally on the both hemispheres
  • Since the sun is shining directly on the northern hemisphere this hemisphere has the warmest temperature
  • The sun is shining equally on the both hemispheres
  • March
  • December
  • September
  • June
