Motion

Question:
1. A straight line passing through the origin on a graph indicates….
2. An object is thrown straight up. Its acceleration at the top of its rise is ……..
3. The slope of a line on a velocity time graph represents …………
4. The MKS unit for force is the …………
5. Neglecting air resistance an object thrown straight up has the same ….. on the way down as it had on the way up.

Answer:

1. Linear variation (is this a velocity time graph? - if so it shows an object starting from rest and accelerating steadily)
2. Equal to g the acceleration of the Earth's gravity - it is always the same if you ignore air resistance
3. Acceleration of the object
4. Newton
5. Acceleration (also the speed at any height going upwards is the same as the speed at any height going downwards)
