Forces & Motion

Question 1

Acceleration (m/s squared)

Answer 1

Change in velocity (m/s) / time taken (s)

Question 2

Force (N)

Answer 2

Mass (kg) x acceleration (m/s squared)

Change of momentum (kg m/s) / time taken (s)

Question 3

Pressure (N/m squared)

Answer 3

Force (N) / area (m squared)

Question 4

Momentum (kg m/s)

Answer 4

Mass (kg) x velocity (m/s)

Question 5

Conservation of momentum

Answer 5

Total momentum before collision = total momentum after collision

Question 6

Turning force/ moment (Nm)

Answer 6

Force (N) x perpendicular distance from pivot (m)

Question 7

Speed (m/s)

Answer 7

Distance (m) / time (s)
