1Question

Which animal below would need the most force to stop moving if all of them were moving at the same speed: a mouse, a cat, or an elephant?

2Question

What kind of motion is shown when a bird flies in a straight line from one tree to another?

3Question

A rabbit runs 12 meters in 4 seconds. What is its speed?

4Question

A fish swims faster in water than a turtle on land. What does this tell you about speed?

5Question

Why does a large dog usually need more food energy than a small bird?

6Question

A horse pulls a cart with a force of 200 newtons. If the cart also has 50 newtons of friction, what is the net force on the cart?

7Question

An owl can turn its head much more easily than a cow can. What does this suggest about flexibility and motion?

8Question

A cheetah runs 90 meters in 3 seconds. A deer runs 60 meters in 3 seconds. Which animal is faster, and by how much?

9Question

Why is a penguin better able to move in water than a land animal with the same body size?

10Question

A crab walks sideways because of the way its legs are attached. How does the arrangement of an animal's body parts affect its motion?

11Question

A kangaroo jumps upward and forward. Name the two main directions of motion in this jump.

12Question

A bee flies 25 meters east, then 10 meters west. What is the bee's total distance traveled?

13Question

An animal's muscles work to move its bones. What simple machine is most like a bone and joint working together?

14Question

A seal moves through water more easily than a box-shaped toy boat. Explain how shape affects motion in water.

15Question

A tiger starts from rest and reaches a speed of 20 meters per second in 4 seconds. What is its average acceleration?

Answer Key

#	Answer
1	The elephant.
2	Straight-line motion.
3	3 meters per second.
4	Speed is the distance traveled in a certain amount of time.
5	Because the larger dog has more body mass and usually needs more energy to move and stay alive.
6	150 newtons.
7	The owl has greater flexibility, so some animals can move parts of their bodies through a larger range of motion.
8	The cheetah is faster by 10 meters per second.
9	A penguin has body features that reduce resistance in water, helping it move more easily and efficiently.
10	The arrangement of body parts affects how an animal moves, what directions it can move, and how efficiently it can move.
11	Upward and forward.
12	35 meters.
13	A lever.
14	A streamlined shape reduces water resistance, so the seal can move more easily than a shape with flat sides.
15	5 meters per second squared.
