---|---|---|---|---|---|
show | familiarity, adrenaline rush,
🗑
|
||||
Define acceleration | show 🗑
|
||||
What 2 properties does a vector quantity have? | show 🗑
|
||||
How do you calculate the acceleration from a velocity time graph? | show 🗑
|
||||
show | accelerate in the direction of the force
🗑
|
||||
show | constant velocity or remain stationary
🗑
|
||||
What is the relationship between force mass and acceleration? | show 🗑
|
||||
show | When two bodies interact, the forces they exert on each other are equal in size and opposite in direction and that these are known as action and reaction forces
🗑
|
||||
show | Falling objects are acted on by a downward force (weight) and an upward force (air resistance) and that at the start of the fall the forces are unbalanced and the object accelerates
🗑
|
||||
What happens to the air resistance as the the speed of an object falling through it increases? | show 🗑
|
||||
When does terminal velocity occur? | show 🗑
|
||||
show | Total distance travelled between seeing reason to stop and stopping. Stopping distance =thinking distance + braking distance
🗑
|
||||
What is thinking distance? | show 🗑
|
||||
show | Distance travelled from time foot hot brakes to when the car stops.
🗑
|
||||
show | Driver drinking, drugs, mobile phone use. Anything that increases the reaction time
🗑
|
||||
show | poor brakes, worn tyres, ice, wet weather, anything that reduces friction between road and tyre
🗑
|
||||
What methods can be used to express risk? | show 🗑
|
||||
show | Imposed - no choice e.g. going to school on bus. Voluntary risk- a choice e.g. skiing, crossing the road not at a zebra crossing.
🗑
|
||||
Describe and explain measures designed to reduce the rate of change of momentum of fragile objects, eg passengers on a rollercoaster | show 🗑
|
||||
show | Force= the rate of change of momentum F= (mv-mu)/t mv = final momentum mu = initial momentum
🗑
|
||||
Explain how seat belts and air bags work? | show 🗑
|
||||
show | The car crumples and absorbs the energy more slowly in the collision. Increasing the collision time, reducing the collision force (rate of change of momentum is reduced).
🗑
|
||||
What is the formula for momentum? | show 🗑
|
||||
show | kg m/s
🗑
|
||||
What is the units of force? | show 🗑
|
||||
What is a unit of acceleration | show 🗑
|
||||
What does the symbol v stand for? | show 🗑
|
||||
show | initial velocity
🗑
|
||||
show | Flight simulators, car design
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
