QuestionAnswer
State the defining equation for newtons second lawF= Mass x acceler
What is the difference between speed and velocity?Speed is scalar (doesn't include direction) Velocity is a vector, so has it direction
What is the equation for speed?Distance/Time
What is the unit used for weight?Newton (N)
What is weight?The force that acts on an object due to gravity and the objects mass.
What are the two categories that all forces can be split into?1.Contact Forces 2.Non-contact forces
What is a force?A push or pull acting on an object due to an interaction with another object
Define massThe amount of matter contained in an object
\What does a curved line represent on a displacement time graph?Acceleration or deceleration
State Newtons third lawWhen two objects interact they exert forces on each other which are equal and opposite
State the defining equation for newtons second lawF= Mass x Acceleration (M x A)
What is Newton's second law for a moving object?The object will remain at constant velocity if no other force acts on it.
What is newtons first law?If the resultant force on a stationary object will remain at rest
What is the equation for momentum?Momentum= Mass x Velocity
What is the gradient of a displacement time graph?Velocity
Give an equation for acceleration(Final velocity - initial velocity)/ Time
