Unit 3 - Force Review

Front

What does it mean when an object is at equilibrium?

Back

It means that there is zero net force on the object.

Front

Can an object with zero net force be non-moving?

Back

True.

Front

Do two objects with the same net force have the same acceleration?

Back

Yes, they both have the same acceleration.

Front

Can an object with a net force on it be moving at a constant velocity?

Back

False.

Front

What is inertia?

Back

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

Front

Do only non-moving objects have inertia?

Back

No, all objects have inertia, both moving and non-moving.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
