Changes In Momentum (physics Only) (GCSE Physics)

Which quantity is conserved for an isolated system in any collision (elastic or inelastic)?

Which statement about impulse is correct?

A force–time graph shows a triangular pulse with peak force 200 N lasting 0.5 s (triangular shape to zero). What impulse is delivered?

A 2.0 kg object moving at 3.0 m/s collides with and sticks to a 3.0 kg object at rest. What is their common speed immediately after collision?

A 4.0 kg cart moving at 2.5 m/s collides elastically with a 1.0 kg cart moving toward it at 1.5 m/s. What is total momentum before collision? (Take right as positive)

A figure shows a car stopping with seatbelt vs without. Which explanation correctly describes why the seatbelt reduces injury?

Which scenario shows momentum is a vector quantity?

During an explosion a stationary shell of mass 10 kg breaks into two fragments of 3 kg and 7 kg which fly apart with velocities +8 m/s and v m/s respectively. What is v?

Two ice skaters push off each other. Before push both at rest; after push one skater of mass 50 kg moves at 1.2 m/s. What is the velocity of the other skater of mass 75 kg? (Conserve momentum)

A 0.50 kg toy car is moving at 4.0 m/s. What is its momentum?

A ball bounces off a wall; contact time with wall is shortened. How does this affect the peak force on the ball (assuming same change in speed)?
