Acceleration Required Practical

What equation links force, mass and acceleration?

• $F\ =\ m\ \times a$
  

• $F\ =\ m\ \div\ a$

• $M\ =\ F\ \times\ a$

• $a\ =\ F\ \times\ m$

What are the units for acceleration?

• m/s

• m/s²

• N

• N/kg

Which of these equations can be used to calculate acceleration?

• $a\ =\ \Delta v\ \div\ t$

• $a\ =\ v\ \times\ t$

• $a\ =\ v^2\ \times\ t$

• $a\ =v\ \div\ t$

What does

 $\Delta$   mean in an equation?

• Change in

• Triangle
  

• Up

• Divide

Which piece of equipment can be used to measure velocity?

• Light gates

• Ruler

• Stop watch

• Thermometer

What do you have to program into the light gate to measure velocity?

• Width of the glider

• Mass of the glider

• Height of the glider

• Shape of the glider

Why do you need two light gates?

• So you can see the change in velocity

• It is more accurate

• It is more precise

• It is less accurate

What does accuracy mean?

• how close to the correct measure they are

• how close measurements cluster together

• how similar are results in the investigation

• how similar results are when the investigation is done by different investigators

What does precision mean?

• how close to the correct measure they are

• how close measurements cluster together

• how similar are results in the investigation

• how similar results are when the investigation is done by different investigators

What does repeatability mean?

• how close to the correct measure they are

• how close measurements cluster together

• how similar are results in the investigation

• how similar results are when the investigation is done by different investigators
