Forces Practice Flashcardizz

Front

What happens to the acceleration of an object if you increase the force applied to it?

Back

The acceleration also increases.

Front

Who is correct: Mac, who says inertia depends on speed, or Tosh, who says inertia depends on mass?

Back

Tosh is correct; inertia depends on mass, not speed.

Front

If a force of 90N is applied to multiple carts, which cart will accelerate the fastest?

Back

The cart with the least mass will accelerate the fastest.

Front

What is the state of a book sitting on a shelf?

Back

The book is in a balanced state.

Front

What does it mean if forces acting on an object are balanced?

Back

The object remains at rest or moves at a constant velocity.

Front

What does it mean if forces acting on an object are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and inertia?

Back

Inertia increases with mass; heavier objects have more inertia.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

If an object is at rest, what can be said about the forces acting on it?

Back

The forces are balanced.
