We have learned about 3-D solid shapes. Now let’s see which 3-d shapes can roll, and which can slide.
- Rolling: To move by turning over and over.
- Objects with curved surfaces roll.
- Sphere shape has a curved surface.
- Ball is an example of a sphere shape. If we just move the ball it will roll.
Which 3-D shapes can roll?
Sphere, Cylinder, Cone shapes have curved surfaces. So, these shapes can roll.
Real-life examples of the objects which can roll.
- Slide: To move objects smoothly along a surface.
- Objects with smooth plane surfaces can slide.
- Cube shape has a plain smooth surface.
- Box is an example of a cube shape. It has a smooth surface. If we push the box, it will slide.
Which 3-D shapes can slide?
- Cube and Cuboid shapes have smooth surfaces. So, these shapes can easily slide.
- But Cone and cylinder shapes can also slide. Cone and cylinder shapes also have smooth plain surfaces.
Real-life examples of the objects which can slide.
- Flipping: To turn over the objects.
- Creating a mirror image is flipping.
There are two types of flipping -
- Vertical flip
- Horizontal flip
Vertical flip: Top side switches to the bottom and bottom side switches
to the top side.
Horizontal flip: In the horizontal flip left side switches to the right
side and right side switches to the left side.
