P5 Forces & Motion 2 (GCSE Physics 9-1 AQA)

Displacement is a

• Scalar quantity
• Vector quantity
• Base quantity
• Derived quantity

A boy of mass 50 kg runs with a force of 100 N, his acceleration would be

• 5000 m s^-2

• 50 m s^-2

• 150 m s^-2

• 2 m s^-2

SI unit for force is

• Kilograms
• Newton
• Joules
• acceleration

Adding of two vectors to get a single vector is termed as

• Final vector
• Resultant vector
• Dominant vector
• Recessive vector

Newton's first law is also known as

• Law of inertia
• Law of momentum
• Law of forces
• Law of zero

Formula of force is

• F = P/A, where P is pressure and A is area
• F = ms, where m is mass and s is speed
• F = ma, where m is mass and a is acceleration
• F = m/v, where m is mass and v is velocity

The state of equilibrium is when

• there is no opposing force
• there is no force acting on an object
• the object is moving in uniform speed
• B and C both

A wooden trolley of mass 20 kg accelerates at 2 m s^-2, if the force due to engine is 50 N, the friction force is equal to
