AQA GCSE chapter 11 Forces and acceleration

Which equation links resultant force, mass and acceleration?

• F = m + a

• F = m x a

• F = m / a

• F = m - a

What is the unit of force in Physics?

• Joule

• Kilogram

• Newton

• Watt

If the mass of an object is doubled but the resultant force stays the same, what will happen to its acceleration?

• It stays the same

• It is doubled

• It is halved

• It becomes zero

The acceleration of an object is proportional to:

• Its mass

• Its volume

• The resultant force on it

• Its speed

A trolley of mass 2 kg is pulled with a resultant force of 4 N. What is its acceleration?

• 2 m/s²

• 4 m/s²

• 1 m/s²

• 8 m/s²

What is the tendency of an object to stay at rest or in uniform motion called?

• Weight

• Inertia

• Gravity

• Elasticity

A force of 10 N gives an acceleration of 5 m/s² to a mass m. What is m?

• 2 kg

• 5 kg

• 0.5 kg

• 50 kg

Which statement about Newton’s Second Law is correct?

• Acceleration is inversely proportional to force

• The greater the mass, the greater the acceleration for a given force

• Acceleration is proportional to resultant force

• Acceleration is always constant

A car of mass 1000 kg accelerates at 3 m/s². What force is needed?

• 3000 N

• 1000 N

• 333 N

• 30,000 N

What is the correct rearrangement of Newton’s Second Law to find mass?

• m = a / F

• m = F / a

• m = F x a

• m = a - F
