Newtons 2nd Law Practice

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. It can be expressed with the formula F=ma.

How do you calculate net force if mass and acceleration are known?

Back

Net force can be calculated using the formula F=ma, where 'm' is mass and 'a' is acceleration.

Front

If a car has a mass of 1,000 kg and accelerates at 3 m/s², what is the net force?

Back

F = ma = 1,000 kg * 3 m/s² = 3,000 N.

Front

What is the relationship between force and acceleration?

Back

Force is directly proportional to acceleration; as force increases, acceleration increases if mass remains constant.

What is the slope of a force vs. acceleration graph?

Back

The slope of a force vs. acceleration graph represents the mass of the object.

If the net force acting on an object is 10 N and its mass is 2 kg, what is the acceleration?

Back

Using F=ma, acceleration a = F/m = 10 N / 2 kg = 5 m/s².

What happens to acceleration if mass increases while force remains constant?

Back

If mass increases while force remains constant, acceleration decreases.
