Newton's Laws, Motion, & Forces

Front

What is Newton's first 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 second law of motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's third law of motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and opposite, causing a change in motion.

Front

What is a noncontact force?

Back

A force that can act on an object without physical contact, such as gravitational force or magnetic force.

Front

What is a contact force?

Back

A force that acts on an object through direct physical contact, such as friction or tension.

Front

How do you calculate force?

Back

Force is calculated using the formula F=ma, where F is force, m is mass, and a is acceleration.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).
