Year 11 Physics Revision Quiz

Describe what is meant by weight.

• The amount of matter in an object

• The gravitational force acting on an object

• How heavy something is

• It is measured in kilograms

What is the unit of weight?

• Newtons

• kilograms

• centimetres

• grams

What is meant by the mass of an object?

• The gravitational force acting on the object

• How heavy an object is

• The amount of matter in an object

• The amount of Newtons

What is the unit of mass?

• kg

• g

• Newtons

• cm

What is Newton's first law?

• An object remains at rest or at constant velocity unless acted on by an unbalanced force

• If body A exerts a force on body B, body B exerts an equal and opposite force on body A

• The resultant force is directly proportional to the acceleration, provided the mass is constant

What is Newton's second law?

• An object remains at rest or at constant velocity unless acted on by an unbalanced force

• If body A exerts a force on body B, body B exerts an equal and opposite force on body A

• The resultant force is directly proportional to the acceleration, provided the mass is constant

What is Newton's third law?

• An object remains at rest or at constant velocity unless acted on by an unbalanced force

• If body A exerts a force on body B, body B exerts an equal and opposite force on body A

• The resultant force is directly proportional to the acceleration, provided the mass is constant

What is meant by terminal speed?

• The fastest speed

• The maximum constant speed when the forces acting on the object are balanced

• When the speed is increasing

• When the speed is decreasing

How is rolling resistance reduced in modern cars?

• Correctly inflate the tyres and use materials that don't heat up as much.

• Use start-stop systems

• More streamlined shapes

• Make the cars more lightweight

How are idling losses reduced in modern cars?

• Correctly inflate the tyres and use materials that don't heat up as much.

• Use start-stop systems

• More streamlined shapes

• Make the cars more lightweight
