Forces and Motion Review

Front

What are balanced forces?

Back

Balanced forces are two equal forces acting in opposite directions on an object, resulting in no change in motion.

Front

What is net force?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, making it harder to move.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Front

What is an example of action-reaction forces?

Back

An example is when a person jumps off a small boat; the action of jumping pushes the boat backward.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.
