How does Newton's third law apply to equilibrium situations?
Acceleration
A body is in equilibrium when the forces acting on it are all balanced, so there is no overall force acting on the body.
What’s the thinking distance?
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
What’s the braking distance?
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
What’s the stopping distance?
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
sum of the distance the vehicle travels during the driver's reaction time (thinking distance) and the distance it travels under the braking force.
How is reaction time can affect thinking distance?
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
Longer reaction times increase the thinking distance when stopping from a given speed.
Describe physical factors that can affect braking distance - condition of tyres, road etc
Weight of the vehicle
Temperature
Speed of vehicle
Sunlight
efficiency of the braking system.
explain why large decelerations are dangerous and estimate values forces involved in deceleration of road vehicles
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
Large decelerations may cause the brakes to overheat, and the driver may also lose control of the vehicle.
Describe the origin and properties of longitudinal waves and examples
Electromagnetic waves
the vibrations are parallel to the direction
Move up and down

Describe the origin and properties of transverse waves and examples
Electromagnetic waves
the vibrations are parallel to the direction

Number of waves passing a point each second
How tall the wave is
Meaning of crest
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
The top of the wave
How tall the wave is
A way of remembering EM waves

Explain how radio waves are generated by oscillating charges in the transmitter and how this generates a current in the receiver?
Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves.
A body is in equilibrium when the forces acting on it are all balanced, so there is no overall force acting on the body.
electrons produce radio waves which are transmitted over as distance. At the receiver, the radio waves cause electrons to oscillate.
Explain how microwaves can be used to communicate with satellites?
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
Longer reaction times increase the thinking distance when stopping from a given speed.
penetrate haze, light rain and snow, clouds, and smoke are beneficial for satellite communication
Explain some of the dangers of EM waves and how the radiation dose is measured
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
It can damage human body tissue
Permanent magnets are what?
Generate their own magnetic fields
Become magnets when they are placed in a magnetic field
Induced magnets are what?
Generate their own magnetic fields
Become magnets when they are placed in a magnetic field
Explain how a current produces a magnetic field
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire.
how a solenoid can increase the strength
The distance travelled by the vehicle because of the braking force
The distance travelled by the vehicle during the driver’s reaction time
It can damage human body tissue
increasing the number of turns on the coil. increasing the current. placing an iron core inside the solenoid.
Explain how the interaction of a magnetic field induce by a current and a magnetic field between a horseshoe magnet can produce movement of the wire
The distance travelled by the vehicle because of the braking force
