Newton's Laws of Motion
This law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.
What is Newton's First Law of Motion?
The acceleration due to gravity near the Earth's surface, approximately 9.8 m/s
What is g?
The region around a magnet where magnetic forces are exerted.
What is a magnetic field?
What is the lowest point of a wave?
What is trough?
This law can be mathematically represented by the equation F=ma.
What is Newton's Second Law of Motion?
The path of a projectile is typically shaped like this.
What is a U shaped/ parabola?
This is the term for materials that do not conduct electricity well
What are insulators?
Give an example of how a sound wave can be absorbed.
What is yapping and eardrum?
For every action, there is an equal and opposite reaction.
What is Newton's Third Law of Motion?
The point where a thrown object reaches its highest position.
Peak
The unit of electric current.
What is an ampere (amp)?
The maximum displacement of a point on a wave from its rest position.
What is amplitude?
The tendency of an object to resist changes in its state of motion
What is inertia?
This occurs when the only force acting on an object is gravity.
What is free fall?
What are the best conductors of electricity
What is copper, metal etc.
Describe how transmission works with sound waves
What is Sound waves pass through materials, efficiency depends on the material.
This force acts between two surfaces and opposes motion.
What is friction?
The path a ball takes when you throw it.
What is the trajectory?
Poor conductors of electricity
What is rubber, plastic etc.
The number of complete cycles of a wave passing a point in one second.
What is frequency?
