Net Force

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration.

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when the total net force acting on an object is zero, resulting in no change in motion.

Front

What happens to an object's acceleration when the net force acting on it increases?

Back

The acceleration of the object increases when the net force acting on it increases, according to Newton's second law of motion.

Front

What is the relationship between mass, force, and acceleration?

Back

According to Newton's second law, the relationship is given by the formula F = ma, where F is the net force, m is the mass, and a is the acceleration.

Front

How do you calculate the mass of an object if you know the net force and acceleration?

Back

You can calculate the mass using the formula m = F/a, where F is the net force and a is the acceleration.

Front

What is the weight of an object?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and the acceleration due to gravity (W = mg).

Front

If an object is accelerating, what can we infer about the forces acting on it?

Back

If an object is accelerating, the forces acting on it are unbalanced, meaning the net force is not zero.

Front

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

Back

The unit of force in the SI system is the Newton (N).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you determine if forces are unbalanced in a free body diagram?

Back

Forces are unbalanced in a free body diagram if the vector sum of all forces does not equal zero, indicating a net force acting on the object.
