F-1 Flashcard

Front

What is friction?

Back

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

Front

What happens to an object's velocity when a net force is applied?

Back

The object's velocity changes; it can either speed up, slow down, or change direction depending on the direction of the net force.

Front

What is a force-time graph?

Back

A force-time graph shows how the force acting on an object changes over time, which can help determine changes in the object's motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

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 object's mass.

Front

What is the relationship between mass 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 is the concept of constant velocity?

Back

Constant velocity means that an object is moving at a fixed speed in a straight line, with no changes in speed or direction.

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion by accelerating them downward.

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 significance of a net force?

Back

The net force is the overall force acting on an object after all the individual forces are combined; it determines the object's acceleration.
