Newton's 2nd Law

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

• F = ma, meaning that force equals mass times acceleration.

• F = m/a, meaning that force equals mass divided by acceleration.

• F = a/m, meaning that force equals acceleration divided by mass.

• F = m + a, meaning that force equals mass plus acceleration.

What does the letter 'm' represent in the formula F = ma?

• The force applied to the object, measured in newtons (N).

• The acceleration of the object, measured in meters per second squared (m/s²).

• The mass of the object, measured in kilograms (kg).

• The distance traveled by the object, measured in meters (m).

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

• The acceleration increases.

• The acceleration decreases.

• The acceleration remains the same.

• The acceleration becomes zero.

How do you calculate the mass of an object using Newton's 2nd Law?

• Mass can be calculated using the formula m = F/a, where F is the net force and a is the acceleration.

• Mass can be calculated using the formula m = a/F, where F is the net force and a is the acceleration.

• Mass can be calculated using the formula m = F * a, where F is the net force and a is the acceleration.

• Mass can be calculated using the formula m = F + a, where F is the net force and a is the acceleration.

What unit is acceleration measured in?

• meters per second (m/s)

• meters per second squared (m/s²)

• kilometers per hour (km/h)

• feet per second (ft/s)

What does the letter 'F' represent in the formula F = ma?

• 'F' represents the net force acting on an object, measured in Newtons (N).

• 'F' represents the mass of the object, measured in kilograms (kg).

• 'F' represents the acceleration of the object, measured in meters per second squared (m/s²).

• 'F' represents the frictional force acting on the object, measured in Newtons (N).

What is the formula for calculating force?

• F = ma

• F = mv

• F = m/a

• F = m + a

What is Newton's 2nd Law of Motion?

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

• An object at rest will stay at rest unless acted upon by an external force.

• The force acting on an object is equal to the mass of the object multiplied by its velocity.

• For every action, there is an equal and opposite reaction.

What is an example of Newton's 2nd Law in everyday life?

• Pushing a shopping cart: the harder you push (more force), the faster it accelerates.

• Dropping a ball: it falls to the ground due to gravity.

• Riding a bicycle: pedaling harder makes the bike go slower.

• Throwing a paper airplane: it glides smoothly through the air.

If a force of 50 N is applied to an object and it accelerates at 10 m/s², what is the mass of the object?

• 3 kg

• 5 kg

• 7 kg

• 10 kg
