Fast Facts Flashcard: Dynamics

Front

What is the single force that can replace all individual forces acting on an object?

Back

Net force

Front

What are the units for mass?

Back

Kilograms (kg)

Front

What is the force of a surface acting perpendicular to an object?

Back

Normal force

Front

What is the acceleration of an object moving at constant speed along a surface in the direction perpendicular to the surface?

Back

Zero

Front

What is the net force on an object in equilibrium?

Back

Zero

Front

What is the force that opposes the motion of an object in contact with a surface?

Back

Friction

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on an object at rest, while kinetic friction acts on an object in motion.

Front

What is the formula for calculating net force?

Back

Net force = mass × acceleration (F = ma)

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = mass × gravity).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.
