Ans:Speed is the distance traveled
divided by the time taken to travel the
distance.
Mass
Mass • An important property of an object is mass.
Mass • An important property of an object is mass.
• The mass of any object is the amount of matter in the objets.
Mass • An important property of an object is mass.
• The mass of any object is the amount of matter in the object.
• Objects with more mass weight more than objects with less mass.
Mass • An important property of an object is mass.
• The mass of any object is the amount of matter in the object.
• Objects with more mass weight more than objects with less mass.
For example a gallon of milk has more mass then a garbage bag.

• The size does not matter. A garbage bag is bigger and the milk is smaller does not mean that the bag has the most mass.

Mass is measured in kg.
Inertia
Inertia• Inertia means; tendency of an object to resist
a change in its motion.
Inertia• Inertia means; tendency of an object to resist
a change in its motion.
• When an object has more mass it has more inertia.
Inertia• Inertia means; tendency of an object to resist
a change in its motion.
• When an object has more mass it has more inertia.
• For example a ping pong ball will responds to a gentle hit. But if a tennis ball was hit gentle it won't go as far.

Momentum
Momentum• Momentum is a measure of how difficult it is
to stop a moving object
Momentum• Momentum is a measure of how difficult it is
to stop a moving object
• The momentum of an object is a measure of how hard it's to stop an object.
Momentum• Momentum is a measure of how difficult it is
to stop a moving object
• The momentum of an object is a measure of how hard it's to stop an object.
• sense mass is measured in kilograms and velocity has units of meters per second,momentum has units of kg times by meters per second.

• Also because velocity and momentum have the same direction.
Conservation of Momentum
Conservation of Momentum
• When you play pool you have to hit a ball (cue ball) to the other balls.When you hit the cue ball at the other balls the cue ball slows down and the momentum decreases
Conservation of Momentum
• When you play pool you have to hit a ball (cue ball) to the other balls.When you hit the cue ball at the other balls the cue ball slows down and the momentum decreases
• and also the other balls you hit speed up and the momentum increases.

• The momentum lost by the cue ball was gained by the other ball.

• and also the other balls you hit speed up and the momentum increases.
• The momentum lost by the cue ball was gained by the other ball.
• So the total momentum of the two balls was the same before and after the collision.
• The law of conservation of momentum is

• The law of conservation of momentum is that the total momentum of objects that collide is the same before and after the collision.
