A marathon runners speed after the whole event is referred to as;
Average Speed
Instantaneous speed
Normal speed
Walking pace
What is instantaneous speed?
The speed at an instant
The speed at any given point in time
The speed on the speedometer of a car
The highest speed
Apply; True or false;
During a race, some instantaneous speed values will be higher than the runners average speed
TRUE
FALSE
Average speed =
(total distance) ÷ (total time)
(total distance) x (total time)
(total time) ÷ (total distance)
Speed x time

What happens when you squash the volume of a gas into a smaller volume? (Select 3 answers)
There will be more molecules because of a higher pressure
There will be more collisions between the molecules and the walls of the container
The pressure increases because there are more collisions
The temperature increases because there are more collisions
What happens when you blow a balloon and place it inside the fridge to decrease its temperature?
The molecules move more slowly
The pressure goes down
There are fewer collisions
The balloon will collapse
The balloon will keep its shape
How come we do not feel the atmospheric pressure pushing on us from all directions around us?
{Select two answers
It cancels itself out
Its cancelled out by the gasses
Its cancelled out by the pressure of the gases and liquids in your body pushing out
It's balanced by our body's internal pressure
The pressure exerted on our bodies by the air around us is known as;
air pressure
gas pressure
pressure
atmospheric pressure
(Select 4 answers)
Which of these are true about atmospheric pressure?;
Gravity pulls the air particles towards the earth
The particles are closer and there are more collisions near the earth's surface
The pressure is higher at the earth's surface
The temperature is higher closer to the earth's surface
The temperature s lower closer to the earth's surface
If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?
The pressure will increase
The pressure will decrease
In all directions
In no direction
there is no pressure
We can increase the pressure of a gas by:
Adding more gas.
Reduce the volume of the container.
Increase the temperature of the gas.
None of the above answers.
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
Why are liquids incompressible?
(Select two answers)
The particles in a liquid are touching each other
There is very little space between the particles
Liquids are similar to solids
They have no where to go
What is "upthrust"?
The force that keeps things afloat
The force than pulls you down in water
The force of the water
The upward current in a lake
What produces upthrust?
Gravity
liquid pressure
Liquid temperature
All of these
What happens to an object when the area in contact with the water is too small? (Select 3 answers)
There is not enough upthrust
The object will not float
There is no upthrust
The object will sink
The force that pushes a submarine up to the surface is called...
Gravity

A
The figure shows a pond with two fish P and Q.
What is the correct relation of the water pressures on fish P and fish Q?
Water pressure on fish Q > Water pressure on fish P.
Water pressure on fish Q < Water pressure on fish P.
Water pressure on fish Q = Water pressure on fish P.
