Forces and Motion

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

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 unless acted upon by a net external force.

Front

What is Newton's 2nd 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 3rd Law of Motion?

Back

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

Front

What is speed?

Back

Speed is the distance traveled per unit of time, often measured in miles per hour (mph) or meters per second (m/s).

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no net force.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.
