Edexcel GCSE Physics Topic 2 Motion and forces overview quiz quiz

Displacement

The mass of an object

The speed of an object

The energy stored in an object

$8\,\text{m/s}$

$20\,\text{m/s}$

$80\,\text{m/s}$

$8000\,\text{m/s}$

The acceleration

The distance

The speed

The force

The speed of the object

The acceleration of the object

The resultant force on the object

The distance travelled

$2\,\text{m/s}^2$

$2.5\,\text{m/s}^2$

$16\,\text{m/s}^2$

$160\,\text{m/s}^2$

The resultant force on an object is equal to its mass multiplied by its acceleration

An object stays at rest or at constant velocity unless a resultant force acts

Forces always act in equal and opposite pairs on two different objects

The total momentum in a closed system is always conserved

$0.2\,\text{m/s}^2$

$40\,\text{m/s}^2$

$5\,\text{m/s}^2$

$500\,\text{m/s}^2$

$2\,\text{N}$

$30\,\text{N}$

$2000\,\text{N}$

$200\,\text{N}$

It stays the same

It increases on the Moon

It decreases on the Moon

It becomes zero on the Moon

Wet roads

Tiredness

Worn tyres

Worn brakes

$125\,\text{kg m/s}$

$1008\,\text{kg m/s}$

$8000\,\text{kg m/s}$

$80000\,\text{kg m/s}$

By greatly increasing the total change in momentum during the crash

By reducing the overall mass of the whole car

By increasing the speed at which the collision happens

By increasing the time over which the momentum changes

It is conserved

It increases

It decreases

It becomes zero
