What is the equation to calculate speed?

speed (m/s) = distance travelled (m)

                    time taken (s)

What is the equation that calculates acceleration?

acceleration (m/s ) =  change in velocity (m/s)

                                      time taken for the change (s)                      

Distance = Speed x Time

Time = Distance

          Speed

Speed = Distance

           Time 

What is the unit of force? 

Newtons (N)

What is a resultant force?

It is a single force that has the same effect as all of the forces acting on the object.

Eg. When the resultant force is 0, the object is either stationary (if it was at rest) or it continues to move at the same speed and in the same direction if it was already moving

Eg. When the resultant force is not 0, the movement of the object depends on the size and direction of the resultant force.

What is the equation that links the resultant force, mass and acceleration together?

resultant force (N) = mass (kg) x acceleration (m/s )

What is the equation for the stopping distance?

stopping distance = thinking distance + braking distance

What is the correct equation for momentum?

momentum = mass x velocity

What is terminal velocity?

When the object reaches a constant velocity, as the drag force on it is equal and opposite to its weight.

Eg. Object falls at a steady pace now, so it has reached its terminal velocity
