What are forces in science ks3?
A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces.
What are the properties of light ks3?
Light travels as waves. These are transverse waves, like the ripples in a tank of water. The direction of vibration in the waves is at 90° to the direction that the light travels. Light travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler.
How many forces are there ks3?
two kinds
There are two kinds, contact and non-contact forces. Types of contact and non-contact forces: Gravity. Electrostatic.
What is a light source ks3?
A source of light makes light. The Sun and other stars, fires, torches and lamps all make their own light and so are examples of sources of light.
What are the four types of forces?
If you remember any of the physics you learned in school, it’s possible you may remember that there are four fundamental forces of nature. They are in no particular order gravity, electromagnetism, the weak nuclear force and the strong nuclear force.
What are the five types of forces?
Types of Forces
| Contact Forces | Action-at-a-Distance Forces |
|---|---|
| Frictional Force | Gravitational Force |
| Tension Force | Electrical Force |
| Normal Force | Magnetic Force |
| Air Resistance Force |
What are the 5 main properties of light?

What are the 5 main characteristics of light?
What Are The 5 Characteristics Of Light?
- Light consists of packets of energy called photons.
- Light is the relatively narrow frequency band of electromagnetic waves.
- Light travels at such a high speed, 3 × 10 8 m/sec.
- Light behaves both as a wave and particle.
- Light travels fast in a vacuum.
