AQA GCSE Physics Unit 2.2

1

What can a force do?

1

What is the unit of force?

1

True or false? Every force has an equal and opposite force.

1

True or false? The resultant force is the product of all forces acting upon an object.

1

Which of these situations could occur if the resultant force was zero?

1

Which of these situations could occur if the resultant force was not zero?

1

How many laws of motion did Newton create?

1

True or false? Force, mass and acceleration are linked by the equation F = ma.

1

What could you do to increase the acceleration of an object?

1

True or false? The thinking distance is the sum of the stopping distance and the braking distance.

1

Which factors increase thinking distance?

1

Which factors increase braking distance?

1

True or false? The gravitational field strength on Earth is roughly 100N/kg.

1

What force is exerted on objects falling in a fluid?

1

What is the terminal velocity of an object?

1

True or false? An elastic object stays permanently deformed, even when the forces deforming it are removed.

1

True or false? Hooke's law states that the extension of a spring is directly proportional to the force applied, providing that the limit of proportionality is not exceeded.

1

What does k stand for in F = ke?

1

True or false? Using a wind deflector increases the amount of fuel needed.

1

True or false? Speed cameras measure the time it takes for a car to travel over a set distance and then the speed is calculated.
