Toys and Forces Forces make toys work Forces make toys start moving change direction speed up slow down and stop moving Forces also change the shape of some toys Bouncing toys Floating toys Flying toys Rolling toys Sliding toys Spinning toys None of these toys would work without forces 4
What Is a Force A force is a push or a pull When you push something it moves away from you When you pull something it moves towards you When this boy applies a pushing force to the toy sailboat it moves away from him When this boy applies a pulling force to the kayak it moves towards him 5
How Does a Floating Toy Work A floating toy can float on water because water pushes up against it The water’s pushing force stops the toy from sinking Many toys that float on water are very light These pool noodles are very light and float because the water pushes them up 6
Some heavier floating toys are shaped so that lots of water pushes up against them The pushing force stops them sinking This model ship floats because its shape lets lots of water push up against it pushing force 7
