How is weight measured?

Using a Newton-meter and scales

The mass on this spring is not moving. Explain what this tells you about the forces acting on it? (select all that apply)

the spring is being stretched by two forces

the bar is pulling the spring upwards

the weight of the mass is pulling the spring downwards

the two forces are in equilibrium

What is the limit of proportionality?

the greatest force that can be applied to a spring before it undergoes inelastic (permanent) deformation

when a spring returns to its original length

What is inertial mass?

Inertial mass is a measure of an object's resistance to acceleration when a force is applied.

Newton's secret 4th law of motion

Inertial mass is a measure of an object's acceleration when a force is applied.

Inertial mass is a mass which is inertial

State the equation for elastic potential energy

elastic potential energy = 1/2 x spring constant x extension 2 Ep = 1/2 Ke 2 Ep = elastic potential energy in joules (J) K = spring constant in newtons per metre (N/m) e = extension in metres (m)

elastic potential energy = 2 x spring constant x extension 2 Ep = 2 Ke 2 Ep = elastic potential energy in joules (KJ) K = spring constant in newtons per metre (N/m) e = extension in metres (m)

Force = Spring Constant x Extension

What do physicists call the turning effect of a force?

Rotational axonal peripheral triangular wrench turning

The pressure in fluid causes a force normal to any surface. What does normal mean?

" Normality is but a point of view"

State the equation for pressure

Pressure (Pa) = force normal to a surface (N) / area of that surface (m squared) p = F/A

pressure = width of the column x density of the liquid x gravity

pressure = height of the column x density of the liquid x gravitational field strength

State the equation for pressure due to a column of liquid

Pressure (Pa) = height of the column (m) x density of the liquid kg/m 3 ) x gravitational field strength (N/kg)

Define distance. Is it scalar or vector?

Distance is a measure of how far an object travels ; It is a scalar quantity

Distance is a distance of how far an object travels a distance; It is a scalar quantity

Distance is a measure of how far an object travels ; It is a vector quantity

What is displacement? What type of quantity is it?

Displacement is a measure of how far something is from its starting position, along with its direction · It is a vector quantity

Displacement is a measure of how far something is from its starting position, along with its direction · It is a Scalar quantity

Displacement is a measure of how far something is from its final position, along with its direction · It is a physical quantity

State the equation that links time, speed and distance travelled

distance travelled (m) = speed (m/s) x time (s) s = vt

speed = distance travelled / time s = vt

speed (m/s) / displacement (m) = time (s) s=vt

What type of motion can be represented on a distance - time graph?

movement with changing direction

State the equation for calculating acceleration

acceleration (m/s 2 ) = change in velocity (ΔV) / time taken (s)

acceleration (m/s 2 ) = distance (m) / time (s)

acceleration (m/s 2 ) = change in velocity (V 2 ) / time taken (s 2 )

State the equation that links final velocity, initial velocity, acceleration and distance

Final velocity 2 - initial velocity 2 = 2 x acceleration x distance

Final velocity 2 - initial velocity 2 = acceleration x distance

State Newton's second law

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object

The second law states that the mass of an object is dependent upon two variables - the net force acting upon the object and the speed of the object

The second law states that the acceleration of an object is dependent upon two variables - the net velocity acting upon the object and the direction of the object

How do you calculate stopping distance?

thinking distance + braking distance

thinking distance / braking distance

thinking distance - braking distance

thinking distance + emotional distance
