Worksheet Overview

QUESTION 1 of 10

Lots and lots of times in your life already you have been speeding up and slowing down: going down the stairs, running down the corridor (oops!), arriving at your friend's house on your bike - just everyday events.

 

Speeding up and slowing down involve forces. In this worksheet, you can join Callum and his chums playing in the park and trying to find out how to make themselves move faster and slower. Everything they do or play on involves forces. See if you can use your knowledge and understanding to work out what's happening.

 

Up, up and away!

Callum pushes his foot down harder on the path as he rides his scooter.

 

Boy riding scooter

Boy on bike

 

Why does he slow down?

the brake pad pushes on the wheel

the brake pad pulls on the wheel

the brakes stop the pedals moving

Sean wants to go faster on his roller blades.

 

Boy on roller blades

 

What should he do?

go uphill

go downhill

go on the grass

Freya is at the top of the slide. She doesn't want to go down too fast.

 

Playground slide

 

What should she do?

sit on a soft coat

go down backwards

hold on to the sides

Milly loves going high on the swing.

 

Girl on swing

 

What can she do to go higher?

sit very still

keep pushing her legs forward

push or pull her legs hard in the direction she wants to go

Charlie is pulling his younger brothers and sister along on a cart. His sister Hannah wants to slow down.

 

Which of Charlie's actions would NOT slow Hannah down?

Charlie pulls harder

Charlie stops running

Charlie pulls them over the grass

Lucas is having fun on the roundabout.

 

Boy on roundabout

 

Now he wants to get off and go on the swing.

 

Which of these would NOT slow the roundabout down?

Lucas should hold his hands in the air

Lucas should put his feet on the ground

Lucas should tuck his hands and feet in

Charlie's sister, Hannah, is trying out one of the funny sit-on horses at the playground.

 

 

What happens to the spring when Hannah sits on the horse?

the spring breaks

the spring squashes

the spring stays the same

When Hannah gets off the playground horse, what happens to the spring?

 

the spring squashes

the spring pops up

the spring isn't affected

Abdul and Nita are having a go on the playground see-saw.

 

 

If Abdul is heavier than Nita, what will he have to do to make the see-saw work properly?

Abdul will have to push harder

Abdul must push gently

He must get Nita to move towards him a little

Abdul must tuck his legs under the see-saw

  • Question 1

Callum pushes his foot down harder on the path as he rides his scooter.

 

Boy riding scooter

 

What will his scooter do?

CORRECT ANSWER
go faster
EDDIE SAYS
If Callum is pushing down harder with his foot on the path he's trying to make his scooter go faster. He is pushing, with more force, against the ground and this extra effort is transferred to his scooter and makes it speed up.
  • Question 2

When Greg presses the brakes on his bike he slows down.

 

Boy on bike

 

Why does he slow down?

CORRECT ANSWER
the brake pad pushes on the wheel
EDDIE SAYS
When Greg pulls on the brakes, the brake pads push on the wheels, squeezing them. The more force he uses on the brakes, the harder the pads push against the wheel which slows his bike down.
  • Question 3

Sean wants to go faster on his roller blades.

 

Boy on roller blades

 

What should he do?

CORRECT ANSWER
go downhill
EDDIE SAYS
If Sean goes on the grass, it's harder to move so he'll slow down. If he goes uphill he's going against gravity and will slow down. But if he goes downhill he's going with gravity and that force will help him to go faster.
  • Question 4

Freya is at the top of the slide. She doesn't want to go down too fast.

 

Playground slide

 

What should she do?

CORRECT ANSWER
hold on to the sides
EDDIE SAYS
If Freya sits on a coat she'll probably go faster as it will make her more slippery! Going down backwards won't make much of a difference, but if she holds to sides of the slide as she goes down, she will be pushing against the slide, slowing herself down. You will learn to call this FRICTION.
  • Question 5

Milly loves going high on the swing.

 

Girl on swing

 

What can she do to go higher?

CORRECT ANSWER
push or pull her legs hard in the direction she wants to go
EDDIE SAYS
If Milly pushes forward with her legs as she is whizzing up, and then tucks her legs in and leans forward as she is going back, she will go higher and higher. By using her body's force, moving backwards and forwards, she can make the swing go faster and higher.
  • Question 6

Boy pulling children on toy truck

 

Charlie is pulling his younger brothers and sister along on a cart. His sister Hannah wants to slow down.

 

Which of Charlie's actions would NOT slow Hannah down?

CORRECT ANSWER
Charlie pulls harder
EDDIE SAYS
If Charlie pulls harder he's using MORE force. Hannah wants him to use less, so that the cart slows down. So Charlie should NOT pull the cart harder because that will speed them up.
  • Question 7

Lucas is having fun on the roundabout.

 

Boy on roundabout

 

Now he wants to get off and go on the swing.

 

Which of these would NOT slow the roundabout down?

CORRECT ANSWER
Lucas should tuck his hands and feet in
EDDIE SAYS
If Lucas tucks his hands and feet in he will be smaller, so the air can slip past him easily and that will make him speed up. If he puts his feet on the ground, that force against the ground will slow him down. If he holds his arms up, he makes a bigger force against the wind, so he'll slow down.
  • Question 8

Charlie's sister, Hannah, is trying out one of the funny sit-on horses at the playground.

 

 

What happens to the spring when Hannah sits on the horse?

CORRECT ANSWER
the spring squashes
EDDIE SAYS
Even Hannah's small weight will be enough to squash the spring a little. Her body is being pulled down by gravity and that force squashes the spring a bit.
  • Question 9

When Hannah gets off the playground horse, what happens to the spring?

 

CORRECT ANSWER
the spring pops up
EDDIE SAYS
When Hannah's weight is lifted off the play horse, the spring (which was squashed) now pops back up to where it was before Hannah started playing on it - there was a force pushing down on it but now that force has been removed. That OK?
  • Question 10

Abdul and Nita are having a go on the playground see-saw.

 

 

If Abdul is heavier than Nita, what will he have to do to make the see-saw work properly?

CORRECT ANSWER
Abdul will have to push harder
EDDIE SAYS
You might have to think a bit about this: Abdul is heavier (greater downward force), so if they do nothing, his side of the see-saw will be on the ground and Nita will be up in the air with her legs dangling! So, to make it work properly, he will have to push harder to compensate for his greater weight pulling it down on his side. If he gets Nita to sit nearer, it will make the problem worse!
