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 a net external force.

Front

What is inertia?

Back

The tendency of an object to resist a change in its motion.

Front

What is an unbalanced force?

Back

A force that causes a change in the motion of an object; it results in acceleration.

Front

What is a balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What does Newton's Second Law of Motion state?

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 the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting their motion.

Front

What is momentum?

Back

The product of an object's mass and its velocity; it is a measure of the motion of an object.

Front

What is the law of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.
