Physics Concepts

Front

what is Force

Back

a push or pull on an object that causes acceleration, such as starting to move, speeding up, changing directions, or slowing down. An example is a roller coaster ride.

describe Isaac Newton's life

Back

was born in England in 1643 and died in 1727 at age 85. He liked school and learning, but his mother took him out of school to work on the family farm. During the Great Plague quarantine, he developed the laws of Motion and gravity by studying space and the planet's movement.

Front

First Law of Motion states

Back

an object at rest stays at rest unless acted upon by an outside force, and an object in motion stays in motion unless acted upon by an outside force. This is also called the law of Inertia, which is an object's tendency to keep doing what it is doing.

Front

what is the difference between contact and non-contact force

Back

Contact force: Applied when two objects touch. Non-contact force: Applied without touching, e.g., magnetic force.

Front

Net force

Back

The combination of all the forces acting on an object.

Front

Balanced force

Back

Equal force applied, resulting in no movement or stationary position.

Front

Unbalanced force

Back

Net force is stronger in one direction, causing motion.

Front

Newton's Second Law of Motion

Back

Force = mass divided by acceleration. Acceleration is directly related to net force and inversely related to mass.

Front

Example of balanced force

Back

30 Newtons right + 30 Newtons left = 0 Newtons or no movement.

Front

Example of unbalanced force

Back

200 Newtons right + 100 Newtons left = 100 Newtons right.
