Newton's Second Law (F=ma) - GCSE Physics

What is the equation for force?

• F = m + a

• F = a/m

• F = m/a

• F = ma

What is the unit of force?

• Kilograms

• Newtons

• Meters

• Seconds

What is the equation for acceleration?

• Acceleration = mass / force

• Acceleration = force / mass

• Acceleration = mass * force

• Acceleration = force * mass

What is the relationship between resultant force and acceleration?

• Exponential relationship

• No relationship

• Directly proportional

• Inversely proportional

If the mass of an object is doubled and the resultant force remains the same, what happens to the acceleration?

• It halves

• It quadruples

• It doubles

• It remains the same

What is the mass of the smaller car in the given scenario?

• 1000 kilograms

• 500 kilograms

• 1500 kilograms

• 2000 kilograms

What is the acceleration of the smaller car with a mass of 500 kilograms?

• 4 meters per second squared

• 1 meter per second squared

• 2 meters per second squared

• 3 meters per second squared

According to Newton's second law, mass is ________ to acceleration.

• Not related

• Exponentially related
