Let’s work through the problems step by step.

First Task: Circle the ball that moves faster.
We have two sets of pictures.
Top row:
- Left picture: A small ramp with a ball on it.
- Right picture: A steeper, taller ramp with the same ball.
→ The steeper ramp will make the ball roll down faster because gravity pulls it harder when the slope is sharper. So, the ball on the right (steeper ramp) moves faster.
Bottom row:
- Left picture: A boy pushing a small ball.
- Right picture: The same boy pushing a much bigger ball.
→ It’s harder to push a big ball — it has more mass and inertia. So the smaller ball (left) will move faster when pushed with the same effort.
So for the top row → circle the
right ball.
For the bottom row → circle the
left ball.

Second Question: Is it easier to push a ball uphill or downhill? Why?
Think about gravity:
- When you push a ball
downhill, gravity helps you pull it down. You don’t need to use as much force.
- When you push a ball
uphill, you’re fighting against gravity — it wants to roll back down. That takes more strength.
✔ So, it’s easier to push a ball
downhill because gravity helps you.

Final Answer:
Circle the ball on the steeper ramp (top right).
Circle the smaller ball being pushed (bottom left).
It is easier to push a ball downhill because gravity helps pull it down.
