8.6A F=MxA Flashcard #3

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 = m × a.

Front

How do you calculate mass using force and acceleration?

Back

Mass can be calculated 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 is the Newton (N).

Front

If a vehicle has a net force of 1,800 N and accelerates at 1.5 m/s², what is its mass?

Back

The mass of the vehicle is 1,200 kg.

Front

What is the force acting on a 1,000 kg elevator in free fall?

Back

The force acting on the elevator is 9,800 N.

Front

How do you calculate force using mass and acceleration?

Back

Force can be calculated using the formula F = m × a, where m is the mass and a is the acceleration.

Front

What is the acceleration of an object if a force of 500 N is applied to a mass of 50 kg?

Back

The acceleration is 10 m/s².

Front

What is the formula to calculate acceleration?

Back

Acceleration can be calculated using the formula a = F / m, where F is the net force and m is the mass.

Front

If a baseball has a mass of 0.15 kg and is struck with a force of 188 N, what is its acceleration?

Back

The acceleration of the baseball is 1,253 m/s².

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only under the influence of gravity, with no other forces acting on it.
