1.17 - know and use the relationship between force, mass and acceleration
Force = mass * acceleration
F = ma
F = ma
1.15 - calculate the resultant forces that act along a line
If there is an unbalanced force, the object will accelerate in the direction of the larger force. → This is the resultant force . To calculate it : 1. Look at which side has the larger force. 2. Subtract them. → The arrow should be pointing towards the larger side. 3. The result is the resultant force. 5N ←◼️ → 10N 10 - 5 = 5N Hence, the object will move forward and the resultant force is 5N.
