8.4 Moving About – Practical Work

 

1. Ticker Timer – Active Physics p37
1. Slow constant velocity
2. Fast constant velocity
3. Acceleration

 

 

2. Newton’s Second Law

1. Masses

   Set up the equipment as shown

		Ticker Timer

 

Trolley

 

 

 

 

 

 

Carrier

 

 

 

 

 

 

2. Use the ticker timer to determine the acceleration of the trolley as seen in the previous prac.
3. Transfer a mass from the trolley to the carrier.
4. Repeat to give a total of 5 runs.
5. Plot hanging weight force (F = mg) against acceleration.
6. Use the graph to determine the total mass of the system (use the gradient)
7. Determine the mass of the trolley
8. Compare to the true mass of the trolley.

 

 

3. Collisions – Active Physics p 92
1. Can use air track or dynamics trolleys.

 

 

4. Inertia
1. Use dynamics trolleys to demonstrate the effects of seatbelts during collisions
