True or false
1. The heavier car would a greater momentum and difficult to stop.
2. Momentum depends on mass and velocity.
3. Four objects where the velocity is zero, the momentum is also zero.
4 a moving car has momentum if it moves twice as fast its momentum would be lower as much.
5. Two cars one twice as heavy as the other moves down a hill at the same time. The heavier car would have a smaller momentum.
6. Things thrown upward always fall at a constant acceleration of 9. 8 m/s^2.
7. As the object goes up,it accelerates.
