Resultant force KS3

The plane is flying. The forces acting on it are all balanced. What does this tell you about the plane's speed?

• its speed is constant

• it is accelerating (it's speeding up)

• it is slowing down (decelerating)

The plane is flying. The forces acting on it are all balanced. What does this tell you about the plane's height?

The person is about jump.

Which sum should you do to calculate the resultant force acting on them?

• 1100 - 800 =

• 1100 ÷ 800 =

• 1100 + 800 =

• 1100 x 800 =
