Quiz on Newton's 3rd Law of Motion

According to Newton's Third Law, what happens when one object exerts a force on a second object?

• The second object exerts a weaker force in the same direction.

• The second object exerts a stronger force in the opposite direction.

• The second object exerts a force of the same strength in the opposite direction.

• The second object does not exert any force.

What is a force pair?

• Two forces of different strengths acting on the same object.

• Two forces of the same strength acting in opposite directions on two different objects.

• Two forces of the same strength acting in the same direction on two different objects.

• Two forces of different strengths acting in opposite directions on one object.

How do balanced forces differ from force pairs?

• Balanced forces act on two different objects, while force pairs act on one object.

• Balanced forces act on one object, while force pairs act on two different objects.

• Balanced forces are always stronger than force pairs.

• Balanced forces act in the same direction, while force pairs act in opposite directions.

What is a force pair?

• Forces exerted by and acting on the same object

• Forces exerted by and acting on two different objects

• Forces that cancel each other out

• Forces that only act in one direction

According to Newton's Second Law, how is force calculated?

• F = m + a

• F = m / a

• F = m × a

• F = a / m

What happens when two objects are acted on by the same strength forces but have different masses?

• They have the same acceleration

• They have different accelerations

• They move in opposite directions

• They stop moving

Why does the little truck slow down more quickly in an accident compared to the big truck?

• The little truck has a greater mass

• The big truck has a smaller mass

• The little truck has a smaller mass and greater acceleration

• The big truck has a greater acceleration

When two objects collide, how does the strength of the pushing force compare to the pushing back force?

• The pushing force is always stronger.

• The pushing back force is always stronger.

• Both forces are equal in strength.

• The forces are unrelated.

Identify the force pair in the situation: A baseball bat hits a ball.

• The bat and the ground

• The bat and the ball

• The ball and the air

• The bat and the player

Describe the difference between a force pair and two balanced forces.

• Force pairs are always unbalanced.

• Balanced forces act in the same direction.

• Force pairs act on different objects, while balanced forces act on the same object.

• Balanced forces are stronger than force pairs.
