Newtons Three Laws of Motion Flashcard

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied. It can be expressed with the formula F=ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What is friction?

Back

Friction is the force that opposes motion between two surfaces in contact.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in a net force of zero.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal and opposite, resulting in a net force that causes an object to accelerate.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p=mv (momentum = mass x velocity).

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting the motion of objects, especially those in free fall.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.
