100
The definition for force.
What is a push or pull?
100
A rolling toy truck slams into a wall and comes to a stop. What type of collision is this an example of?
What is inelastic?
100
A truck is moving along the highway with a large amount of momentum. If the truck slows to half of its speed how does this affect the net momentum of the truck?
What is the net momentum decreases by half?
100
A rollercoaster that has a mass of 2000kg is traveling at a velocity of 1m/s. What is its momentum?
What is 2000 kg*m/s?
100
A car traveling at -6m/s has a momentum of -300kg*m/s. What is it's mass?
What is 50kg?
200
The difference between mass and weight.
What is mass is how much matter an object has independent of gravity and weight depends on gravity?
200
One object is moving at a velocity of 4m/s East and collides with another stationary object of the same mass. Explain the expected momentum of each object, the overall momentum and direction of movement after the inelastic collision.
What is the objects will both be moving at 2m/s each, the overall momentum will be 4m/s, and the objects will be moving East?
200
In a dodgeball game a thrown ball comes in contact with a player running forward at the same speed. Compare the momentum of each before the collision and the general momentum of each after the collision.
What is the momentum of the player is greater originally because the player has more mass. The ball moves in the opposite direction with more speed than the player who slightly moves in the other direction?
200
A 5-N force is applied to a 3-kg ball to change its velocity from +9 m/s to +3 m/s. This impulse causes the momentum change of the ball to be ____ kg•m/s.
What is 18 kg*m/s?
200
A 90,000g elephant is running with a momentum of 1080 kg*m/s. What is the elephant's velocity?
What is 12m/s?
300
The definition for momentum.
What is moving inertia?
300
A soccer player with a large amount of mass runs into a stationary player with a smaller mass as he is dribbling the ball. Explain the momentum of each player after the collision.
What is the player with the larger mass will transfer most of the momentum to the player with the smaller mass. The larger player will slow down and the smaller player will accelerate?
300
A boy gets mad at his brother and drops his two favorite toys (a hot wheels car and his xbox) out the window. Which toy has greater momentum?
What is the xbox?
300
A 9520g dog is running at the velocity of 5m/s. What is its momentum?
What is 47.6 kg*m/s?
300
A mother sees her child in the street and runs to grab the child out of the danger of a car traveling in his direction. The mothers momentum before the collision is 40kg*m/s. What is mothers and child's combined momentum afterwards?
What is 40 kg*m/s?
400
The equation and units for momentum.
What is mass times velocity and kg*m/s?
400
A tractor trailer truck is involved in a head on collision with a mini van. Explain which will experience the bigger force.
What is both experience the same force because they are in contact with one another for the same amount of time?
400
A wad of chewed bubble gum is moving with 1 kg*m/s when it collides with a heavy box that is initially at rest. The gum sticks to the box and both are set in motion with a combined momentum that is?
What is 1 kg*m/s?
400
An object moving with a mass of 50g at 20m/s collides with a stationary object of 30g. What is the overall momentum after the collision?
What is 1 kg*m/s?
400
A truck with a mass of 4000g is traveling at a velocity of 20mi/hr. What is its momentum? 1mi=1600m
What is 35.6kg*m/s?
500
The term used for the amount of force and time that force is applied to change momentum.
What is impulse?
500
When objects are in elastic collisions they produce more damage than when they are in inelastic collisions. Explain why?
What is when objects are in contact with one another for a longer amount of time it decreases the amount of force the objects experience and vice versa?
500
A ball is dropped from the same height upon various flat surfaces. The ball bounces back quickly on the first surface, bounces back in a longer amount of time on the second surface, and takes a while to bounce back on the third surface. Compare the amount of force each experience.
What is the ball that stays in contact with the ground the longest experiences the least amount of force and the balls experience more force as they stay in contact with the ground smaller amounts of time?
500
An object that is 100kg and traveling at 2m/s collides with an object that is 80kg traveling -40m/s. What is the momentum after the collision?
What is -3000 kg * m/s?
500
A go cart with a mass of 10kg traveling at 2m/s collides with another go cart of the same mass traveling at -1m/s. What is the net momentum of both of the go carts after the collision?
What is 10kg*m/s?
