F = MA & Potential/Kinetic Energy

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula F = MA.

Front

How do you calculate net force?

Back

Net force is calculated by multiplying the mass of an object by its acceleration (F = MA).

Front

What is the formula to find mass using net force and acceleration?

Back

Mass can be found using the formula M = F/A, where F is the net force and A is the acceleration.

Front

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

Back

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

Front

If a box has a mass of 10 kg and is accelerating at 3 m/s², what is the net force?

Back

30 N (calculated using F = MA: 10 kg * 3 m/s² = 30 N).

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 MV², where M is mass and V is velocity.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, commonly calculated using the formula PE = MGH, where M is mass, G is the acceleration due to gravity, and H is height.

Front

How do you convert grams to kilograms?

Back

To convert grams to kilograms, divide the number of grams by 1000.

Front

What is the acceleration of an object if a net force of 50 N is applied to a mass of 10 kg?

Back

5 m/s² (calculated using A = F/M: 50 N / 10 kg = 5 m/s²).

Front

What happens to the acceleration of an object if the mass increases while the net force remains constant?

Back

The acceleration decreases because acceleration is inversely proportional to mass (A = F/M).
