Net Forces and Free Body Diagrams

Front

What does Newton's 2nd Law state about the relationship between force, mass, and acceleration?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is expressed as f = ma.

Front

What is the force that acts downward on all objects due to gravity?

Back

Gravity.

Front

What is the force exerted by a surface to support the weight of an object resting on it?

Back

Normal Force.

Front

What is the term for the total force acting on an object when all individual forces are combined?

Back

Net Force.

Front

If an object has a net force of 70 N to the right, what can be inferred about the forces acting on it?

Back

The total forces acting to the right exceed those acting to the left by 70 N.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

How does increasing the mass of an object affect its acceleration when a constant force is applied?

Back

Increasing the mass decreases the acceleration, as acceleration is inversely proportional to mass.

Front

What is the significance of free body diagrams in physics?

Back

Free body diagrams visually represent all the forces acting on an object, helping to analyze the net force and motion.

Front

What type of force opposes the motion of an object sliding on a surface?

Back

Friction.

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces result in no change in motion; the object remains at rest or continues to move at a constant velocity.
