|---|---|---|---|---|---|
| show | The object will return to its original shape when the force is removed.
🗑
|
||||
| show | The object will keep their new shape when the force is removed.
🗑
|
||||
| show | The object can be hammered into shape.
🗑
|
||||
| How do you calculate the extension of a spring? | show 🗑
|
||||
| show | If one quantity doubles so does the other.
🗑
|
||||
| show | The quantities do not produce a straight line graph.
🗑
|
||||
| show | Spring or wire at low forces.
🗑
|
||||
| show | Rubber band.
🗑
|
||||
| If a spring extends 2 cm when 10 N are added , how much will extend when 30 N are added? | show 🗑
|
||||
| show | 25cm
🗑
|
||||
| What does the term elastic mean? | show 🗑
|
||||
| show | When the force is removed they keep their shape.
🗑
|
||||
| What does the term malleable mean? | show 🗑
|
||||
| show | The force applied is directly proportional to the extension.
🗑
|
||||
| show | Force has gone up by a factor of 3, so extension will go up by a factor of 3, so 9cm.
🗑
|
||||
| show | It is a straight line through the origin .
🗑
|
||||
| show | spring
🗑
|
||||
| What is the equation in words that relates force to extension? | show 🗑
|
||||
| show | F = k x X
🗑
|
||||
| show | Energy transferred = ½ x spring constant x (extension)2
🗑
|
||||
| show | Pascal
🗑
|
||||
| show | to the surface
🗑
|
||||
| show | Pressure = force normal to the surface/ area of surface
🗑
|
||||
| show | Liquids and gases
🗑
|
||||
| show | 100,000Pa
🗑
|
||||
| show | It increases.
🗑
|
||||
| show | Decreases
🗑
|
||||
| show | IT HAS A HIGHER DENSITY
🗑
|
||||
| show | As their weight is spread over a large area and so the pressure is reduced.
🗑
|
||||
| show | Sharp knife has a smaller surface area, so the pressure is greater so cuts more easily.
🗑
|
||||
| show | Pressure = force normal to the surface/ area
🗑
|
||||
| What is the equation for the pressure due to a column of liquid? | show 🗑
|
||||
| If the density of water is 1000kg/m3 and g=10N/kg, what is the pressure due to water at a depth of 5m? | show 🗑
|
||||
| What is the cause of the upthrust force? | show 🗑
|
||||
| show | Upthrust = weight of the fluid displaced.
🗑
|
||||
| show | Fill up a displacement can until it stops overflowing (1) Measure the mass of an empty measuring cylinder, put under the spout (1) Gently put the object in the can and let the water flow into the measuring cylinder(1). Measure the mass of measuring cylin
🗑
|
||||
| If an object is floating what is the relationship between the weight and the upthrust? | show 🗑
|
||||
| show | Weight is greater than the upthrus.
🗑
|
||||
| Why can a hot air balloon rise? | show 🗑
|
||||
| show | As it floats weight = upthrust
Upthrust = weight of the fluid displaced = mass of fluid x g
= (density of water x volume displaced) x g
= 1000kg/m3 x (2m x2m x 1m) x 10N/kg= 40 000N
🗑
|
||||
| show | Newtons per meter (N/m)
🗑
|
||||
| show | Metres (m)
🗑
|
||||
| show | elastic deformation or elastic behaviour
🗑
|
||||
| When a spring is stretched and its length is permanently altered it is known as | show 🗑
|
||||
| The limit of proportionallity of a spring is… | show 🗑
|
||||
| show | teacher to draw on board…
🗑
|
||||
| show | F=ke
🗑

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.
