3,000 kilograms. Both animal charges at

each other at the same acceleration.

Which animal will have more kinetic energy

(aka Force)?

The elephant will have more kinetic

each animal?

Mass affects force because a larger mass

will produce more force and a smaller

mass will produce less force.

3. Describe what would happen to the

elephant and rhino from question 1 if the

two animals collided.

When the animals collide, the elephant will

push the rhino backwards because the

elephant has more force due to a larger

mass.

4. If you had to ride the elephant or rhino

during the collision, which one would be

safer for you?

I would ride the... because it is safer due

to...

4. If you had to ride the elephant or rhino

during the collision, which one would be

I would ride the elephant because it is

safer due to having a larger mass

compared to the rhino.

an ice road and a cement road. Describe

the difference in friction on both surfaces.

The cement road has more friction

compared to the ice road.

The ice road or the cement road, explain

because...

The ice road or the cement road, explain

The ball will go further on the ice road

because it has less friction to slow the ball

down.

What must you do in order to have the

ball on the cement road roll as far as the

ball on the ice road?

I must ___ so the ball on the cement road

will roll as far as the ball on the ice road.

12. Using your answer from question 10,

What must you do in order to have the

ball on the cement road roll as far as the

ball on the ice road?

I must apply more force (kick harder) so the

ball on the cement road will roll as far as the

ball on the ice road.
