Question 1
An object of mass 0.2 kg has a momentum of 1.2 kg m/s. What is its velocity, in m/s?
Answerm/s
Question 2
A velocity–time graph rises in a straight line from (0 s, 0 m/s) to (4 s, 8 m/s). How far does the object travel in this time, in m?
Answerm
Question 3
A lorry (truck) and a bicycle move at the same velocity. Which has more momentum?
- A. they are equal
- B. the bicycle
- C. neither has momentum
- D. the lorry (truck), because it has more mass
Question 4
What is the momentum of a 60 kg object moving at 15 m/s, in kg m/s?
Answerkgm/s
Question 5
Velocity–time graph: (0 s, 0 m/s) → (4 s, 8 m/s) → (14 s, 8 m/s) → (18 s, 0 m/s). What is the total distance travelled, in m?
Answerm
Question 6
A train travels at a constant 10 m/s for 20 s. On a velocity–time graph, what is the area under the line, and so the distance travelled, in m?
Answerm
Question 7
An object of mass 0.5 kg has a momentum of 4 kg m/s. What is its velocity, in m/s?
Answerm/s
Question 8
A velocity–time graph rises in a straight line from (0 s, 0 m/s) to (4 s, 4 m/s). How far does the object travel in this time, in m?
Answerm
Question 9
A 0.15 kg ball moving at 20 m/s and a 60 kg runner moving at 0.05 m/s — which has more momentum?
- A. the ball
- B. the runner
- C. they have the same momentum
- D. neither has any
Question 10
What is the momentum of a 70 kg object moving at 3 m/s, in kg m/s?
Answerkgm/s
Question 11
Velocity–time graph: (0 s, 0 m/s) → (4 s, 12 m/s) → (14 s, 12 m/s) → (24 s, 0 m/s). What is the total distance travelled, in m?
Answerm
Question 12
A train travels at a constant 10 m/s for 30 s. On a velocity–time graph, what is the area under the line, and so the distance travelled, in m?
Answerm
Question 13
An object moving at 3 m/s has a momentum of 0.6 kg m/s. What is its mass, in kg?
Answerkg
Question 14
A velocity–time graph rises in a straight line from (0 s, 0 m/s) to (10 s, 30 m/s). How far does the object travel in this time, in m?
Answerm
Question 15
Two identical trolleys move towards each other at the same speed. What is their total momentum?
- A. double one trolley's momentum
- B. it cannot be worked out
- C. half one trolley's momentum
- D. zero
Question 16
What is the momentum of a 0.5 kg object moving at 20 m/s, in kg m/s?
Answerkgm/s
