Reporting Period Review Part 1 (24-25)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Define net force.

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is the formula to calculate mass using force and acceleration?

Back

Mass = Force / Acceleration.

Front

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

Back

Newton (N).

Front

What happens to the motion of two objects when they push away from each other according to Newton's law of action-reaction?

Back

They move away from each other at the same speed and go the same distance if they have the same mass.

Front

What is the acceleration of an object if a net force of 10 N is applied to a mass of 2 kg?

Back

Acceleration = Force / Mass = 10 N / 2 kg = 5 m/s².

Front

What is an example of an action-reaction pair in a rocket launch?

Back

Rocket pushing down on the gas from the reaction and the gas pushing up on the rocket.

Front

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

Back

Net force is the vector sum of all the forces acting on the object.

Front

What is the relationship between mass, acceleration, and force?

Back

According to Newton's second law, Force = Mass x Acceleration.

Front

What is the mass of an object if it experiences a force of 300 N and accelerates at 3 m/s²?

Back

Mass = Force / Acceleration = 300 N / 3 m/s² = 100 kg.
