Force, Friction and Gravity Flashcard

Front

What is force?

Back

A push or pull on an object that can cause it to change its motion.

Front

What is friction?

Back

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

Front

What are the types of friction?

Back

1. Static friction: prevents motion. 2. Sliding friction: opposes sliding motion. 3. Rolling friction: opposes rolling motion. 4. Fluid friction: opposes motion through a fluid.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What happens when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and speed.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What is sliding friction?

Back

The resistance encountered when one surface slides over another.
