F-1 Flashcard

Front

What happens to an object when no net force acts on it?

Back

An object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, 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 does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is the effect of applying a force in the opposite direction of motion?

Back

Applying a force in the opposite direction of motion will decrease the object's velocity.

Front

What is Newton's first law of motion?

Back

An object will remain at rest or in uniform motion in a straight line unless acted upon by a net external force.

Front

What is the role of a net force in motion?

Back

A net force is the overall force acting on an object, determining its acceleration and direction of motion.

Front

What happens to a moving object when the applied force is removed?

Back

The object will eventually slow down due to friction and other opposing forces until it comes to a stop.

Front

What is the definition of mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.
