7th Ch. 2 Motion, Forces, and Newton's Laws Pre/Post Flashcardizz

Front

What happens to the net force when balanced forces act on an object?

Back

The net force is zero.

Front

What is the term for an object's tendency to resist changing its motion?

Back

Inertia.

Front

What is described by a change in motion?

Back

Acceleration.

Front

What does Newton's third law of motion state?

Back

When a force is applied on an object, there is an equal force applied by the object in the opposite direction.

Front

What factors affect the strength of the gravitational force between two objects?

Back

The mass of the objects and the distance between them.

Front

What is the definition of force?

Back

A push or pull on an object.

Front

What is inertia?

Back

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

Front

How is acceleration calculated?

Back

Acceleration is calculated by dividing the change in velocity by the time taken.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is Newton's first law of motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by a net external force.
