Force Diagrams & Motion

Front

What is a force diagram?

Back

A visual representation showing all the forces acting on an object, including their direction and magnitude.

Front

What forces are acting on a dropped object near Earth's surface?

Back

The force of gravity acting downward.

Front

What does it mean when an object is speeding up?

Back

It means the object's velocity is increasing over time.

Front

What is the role of air resistance in force diagrams?

Back

Air resistance opposes the motion of an object, but can often be negligible in force diagrams for falling objects.

Front

What forces are acting on a sled being pulled across ice?

Back

The tension in the rope pulling the sled and the frictional force opposing the motion.

Front

What is the net force?

Back

The overall force acting on an object after all the individual forces are combined.

Front

How do you determine the direction of motion from a force diagram?

Back

The direction of the net force indicates the direction of motion.

Front

What happens to a ball just after it has been kicked upward?

Back

The ball experiences an upward force from the kick and a downward force due to gravity.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
