F=ma

The equation that connects force, mass and acceleration is....

• F = a ÷ m

• F= m ÷a

• F= m × a

• F = m + a

To calculate F_net

• F_{net = m x a}

• F_{net = m ÷ a}

• F_{net = a ÷ m}

• F_{net = m + a}

An object is travelling at constant speed.

• Thrust and friction forces are equal and opposite

• Thrust force > Friction force

• Friction force > Thrust force

• Thrust and friction forces are equal and act in the same direction

An object is accelerating.

• Thrust and friction forces are equal and opposite

• Thrust force > Friction force

• Friction force > Thrust force

• Thrust and friction forces are equal and act in the same direction
