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:

Step1: Analyze the first statement

If two forces are in the same direction, they add up, not cancel each other out.

Step2: Analyze the second statement

According to Newton's second law \(F = ma\), if \(F_{net}=0\), then \(a = 0\).

Step3: Analyze the third statement

From \(F=ma\), for the same \(a\), larger \(m\) (heavier object) requires larger \(F\).

Step4: Analyze the fourth statement

The net force acting on an object is equal to its mass times its acceleration (\(F_{net}=ma\)), not all forces (as there can be balanced forces).

Step5: Analyze the fifth statement

By Newton's third law, action - reaction forces act on two different objects.

Answer:

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