F-1 Flashcard

Front

What is a force-time graph?

Back

A graphical representation that shows how force changes over time, indicating when forces are applied and their magnitude.

Front

When is the velocity of an object changing?

Back

The velocity of an object is changing when there is a net force acting on it, as indicated by a non-zero value on a force-time graph.

Front

What does it mean if an object is slowing down?

Back

An object is slowing down when the net force acting on it is in the opposite direction of its motion.

Front

What happens to an object's motion when no net force is acting on it?

Back

If no net force is acting on an object, it will either remain at rest or continue moving at a constant velocity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; it can cause an object to start moving, stop moving, or change direction.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two or more 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 a force applied in the opposite direction of motion?

Back

A force applied in the opposite direction of motion will decrease the object's velocity, causing it to slow down.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it depends on the object's mass.

Front

How does mass affect the motion of an object?

Back

The greater the mass of an object, the more force is required to change its motion.
