equal and opposite
equal
opposite
bigger and better
Complete the statement:
When an object is pushed, it __________________ with an equal and opposite force.

Every time your cat’s paw hits her toy string, it swings away from her. How does this demonstrate Newton’s third law of motion?
Objects with mass, such as your cat's paw and toy string, will require inertia
Objects in action, such as the string toy, will experience force.
For every motion from your cat's paw, there is unbalanced inertia form the string
For every action your cat makes, there is an equal and opposite reaction from the string.
