Newton's 3rd law

Front

What is the definition of a force?

Back

A force is a push or pull that can cause an object to accelerate.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) is calculated using the formula: a = F/m, where F is the net force and m is the mass of the object.

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What are the two types of forces mentioned in the quiz?

Back

Friction and gravity are both examples of forces.

Front

How do you calculate the net force acting on an object?

Back

Net force is calculated by summing all the forces acting on an object, taking into account their directions.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

As mass increases, acceleration decreases if the net force remains constant, according to Newton's second law.

Front

What is an example of an action-reaction pair?

Back

An example of an action-reaction pair is a person pushing against a wall; the action is the push, and the reaction is the wall pushing back.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What happens to an object's motion when the net force acting on it is zero?

Back

If the net force is zero, the object will remain at rest or continue to move at a constant velocity.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force.
