Forces and Movement: Changing Speed

Vocabulary flashcards covering forces, movement, and changing speed from primary science lessons.

Speed

How fast you are moving.

Speeding up

The act of going faster.

Slowing down

The act of going slower.

Force

The cause of an object speeding up or slowing down.

Pedals

The parts on a bicycle that you push on to go faster.

Brakes

The parts on a bicycle that you pull on to go slower.

Asking questions

An important part of science used to investigate how things move and change speed.

Blow the ball

A science activity in which a ball is pushed and blown to investigate changing speed.

Air push

The pushing force created by blowing towards a moving ball that causes it to go slower.

Sticky notes

The materials needed for the 'Think like a scientist 1' activity on asking questions about speed.

Dai's question cards

Cards used to construct scientific questions asking how to make objects go faster or go slower.

Looking for patterns

Observing experimental results to identify consistent trends in how forces change speed.

Investigating carefully and safely

An essential scientific practice followed while conducting experiments on forces and movement.

Ball

The specific item needed to carry out the 'Blow the ball' activity in 'Think like a scientist 2'.

Faster

Moving at a higher speed.

Slower

Moving at a lower speed.
