Newton's Laws, Friction & Momentum Flashcard

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define Inertia.

Back

Inertia is the tendency of an object to resist a change in motion.

Front

What are Balanced Forces?

Back

Balanced Forces are two forces acting in opposite directions on an object, and equal in size.

Front

What is the formula for Newton's 2nd Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

Calculate the FORCE using F=ma if mass = 10 kg and acceleration = 20 m/s².

Back

200 Newtons.

Front

What is the definition of Friction?

Back

Friction is the force that opposes the motion of an object.

Front

What is Momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

What is the difference between Mass and Weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What are Unbalanced Forces?

Back

Unbalanced Forces are forces that cause an object to accelerate because they are not equal in size and opposite in direction.

Front

What does the term 'Net Force' mean?

Back

Net Force is the total force acting on an object when all the individual forces are combined.
