What is the equation to find speed?
Speed = Distance % Time
What is the equation for distance?
Distance = Speed x Time
When drawing a distance - Time graph which axis should Time go on?
Time should go on the x axis.
What is acceleration?
Acceleration is a change in speed it could be an increase or decrease or a chance in direction, so if something travelled in a constant speed in a circle, it would be accelerating!
If the various forces acting on an object add up to zero, which one of these could be true?
a) It is accelerating.
b) It is travelling in a straight line at a steady speed.
c) It is slowing down and will shortly be at rest.
b) It is travelling in a straight Line at a steady speed.
which of these best describes average speed?
a) the overall distance travelled divided by the time taken
b) The reading of the speedometer of a car travelling at top speed
c) The time taken to travel the total journey divided by the total distance
a) The overall distance travelled divided by the time taken
Which of these ending to this sentence is correct?
The greater the speed of an object…
a) …the less time it will take to cover a set distance.
b) …The longer it will take to cover a set distance.
c) …the smaller the distance it will covering a set time
d) …the greater the mass of an object.
a) the less time or will tame to cover a set distance
which of these enables us to calculate the weight of an object?
a) mass / gravitational field strength
b) mass x gravitational field strength
c) gravitational field strength / mass
d) gravitational field strength + mass
b) mass x gravitational field strength
which of these is completely correct?
a) mass is measured in N; weight is measured in N
b) mass is measured in N; weight is measured in kg
c) mass is measured in kg; weight is measured in N
d) mass is measured in kg; weight is measured in kg
c) mass is measured in kg; weight in N
