Newton's Laws

Front

What is the Law of Inertia?

Back

The Law of Inertia is Newton's 1st law, which states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

What direction does friction act in relation to movement?

Back

Friction acts in the opposite direction of movement.

Front

What does 'Forces come in pairs' represent?

Back

This represents Newton's 3rd law of motion.

What does 'For every action, there is an equal and opposite reaction' mean?

Back

This is a statement of Newton's 3rd law, indicating that forces always occur in pairs.

Which car is accelerating?

Back

A car that rounds a curve at a constant speed is accelerating because its direction is changing.

Front

What is Newton's 2nd law?

Back

Newton's 2nd law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

Define mass in the context of Newton's laws.

Back

Mass is a measure of the amount of matter in an object, which affects how much it resists acceleration when a force is applied.

Front

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

Back

According to Newton's 2nd law, the relationship is defined by the equation F=ma, where F is force, m is mass, and a is acceleration.

What is an example of Newton's 1st law in everyday life?

Back

A passenger lurching forward in a car when it suddenly stops is an example of Newton's 1st law.

Front

What is the significance of the net force?

Back

The net force is the total force acting on an object, determining its acceleration according to Newton's 2nd law.
