Newton's Laws Flashcard

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the definition of friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is the formula for calculating force?

Back

F = mass * acceleration.

Front

What is inertia?

Back

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

Front

What does it mean when we say friction acts in the opposite direction of movement?

Back

It means that friction opposes the direction in which an object is moving.

Front

If a 10 kg object accelerates at 5 m/s², what is the force acting on it?

Back

50 Newtons.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is an example of Newton's 1st Law of Motion?

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does friction affect motion?

Back

Friction slows down or stops the motion of an object.

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects towards the center of the Earth, affecting their motion.
