Scalar
Measurable quantity that has only magnitude
Equilibrium
Situation in which there is no resultant force on an object
Elastic Deformation
When a spring is stretched and can return to its original length are the force is removed
Braking Distance
Distance travelled by a vehicle after the driver has reacted to an event on the road
Displacement
Distance moved in a particular direction
Crumple Zone
An area of a car that is designed to deform and crumple in a collision
Balanced Force
When two or more forces act on a body giving zero resultant force
Extension
The increase in length of an object when a force is applied
Momentum
The product of mass and velocity of an object
Plastic Deformation
When a spring is stretched and cannot return to its original shape when the force is removed
Acceleration
The rate at which an object speeds up
Compression
The effect on a spring when a pushing force is applied
Resultant Force
Single force that would have the same effect as all the forces acting on that object
Velocity
Speed at which an object is moving in a particular direction
Inertia
The natural tendency of an object to resist a change in its velocityRw
Reaction Time
Time it takes a vehicle driver to respond to a danger on the road
Air Resistance
