1. When do you get zero resultant force?

• When all the forces act in opposite directions
• When there are no other forces
• When all the forces are balanced
• When the push is stronger than the pull
1 of 5

2. Name two factors which affect acceleration

• Mass and size of force
• Size of force and speed
• Mass and speed
• Weight and direction

3. What is the resultant force?

• The single force which has the same effect on the object as all the individual forces acting together.
• The single force which has the opposite effect as all the forces acting on it.
• The opposite force.
• The force which pushes an object back.

• F=A/P
• F=MxA
• F=PxA
• F=M/A

5. What does the non-zero resultant force do to the object?

• Nothing
• The object travels in the direction of the resultant force or accelerates in the direction of the resultant force
• The object becomes stationary
• The object travels in the opposite direction to the resultant force

Correction

Remember that in an equation:

small letter m is used for mass

small letter a is used for acceleration

To improve this quiz include the units:

F stands for force in newtons (N)

a stands for acceleration in metres per second squared (m/s2)

m stands for mass in kilo gram (Kg)
