GCSE AQA Combined Physics - Forces HT

Scalar quantities only have

(a)  

Vector quantities have both magnitude and...

(a)  

Which of these is NOT a non-contact force?

• Gravity (weight)

• Air-resistance

• Magnetic

• Electrostatic

The weight of an object depends on its mass and the (a)   field strength

What is the weight of an 85 kg man, on Earth, where the gravitational field strength = 9.8N/kg

• 85 kg

• 85N

• 833 kg

• 833N

A person's weight will be less on the Moon as its gravitational field strength is (a)  

An object's weight seems to act at a single point called the...

• centre of attention

• centre of weight

• centre of mass

• centre of force

The single force which has the same effect on an object as the sum of the seperate forces is called the (a)   force

A car has a driving force of 2000N forwards and resistive forces of 1300N backwards. What is the resultant force acting on the car?

• 700N forwards

• 3300N forwards

• 700N backwards

• 3300N forwards

What is the name of the diagrams, showing the forces acting on a body, drawn to scale.

A ____-____ diagram
