Forces and Force Diagrams

Front

What describes how fast an object is moving?

Back

Speed is the measure of how fast an object is moving.

Front

What is inertia a fancy name for?

Back

Inertia is a property of matter that is directly related to mass.

Front

How heavy is one Newton of force?

Back

One Newton of force feels about as heavy as an apple.

Front

What is a Newton a unit of?

Back

A Newton is a unit of force.

Front

What do we call a push or pull exerted on an object?

Back

A push or pull exerted on an object is called a force.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the relationship between mass and inertia?

Back

Inertia is the resistance of an object to change its state of motion, and it is directly proportional to the mass of the object.

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces are combined.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the motion of an object; the object remains at rest or continues to move at a constant velocity.
