Question

true or false
true if two forces are in the same direction they cancel
false each other out
true an object can never have acceleration if the net force
false is zero
true heavier objects require more force to accelerate than
false lighter objects
true the forces acting on the object is equal to its mass
false times its acceleration
true action and reaction forces acts on two different
false objects

Explanation:

• For the first statement: Forces in the same direction add up, not cancel. So it's false.
• For the second statement: According to Newton's second law \(F = ma\), if \(F_{net}=0\), then \(a = 0\). So it's true.
• For the third statement: From \(F=ma\), for the same \(a\), larger \(m\) (heavier object) needs larger \(F\). So it's true.
• For the fourth statement: The net force acting on an object is equal to its mass times its acceleration (\(F_{net}=ma\)), not all forces. So it's false.
• For the fifth statement: Action - reaction forces (Newton's third law) act on two different objects. So it's true.

Answer:

1. FALSE
2. TRUE
3. TRUE
4. FALSE
5. TRUE
