How to increase friction?
We can increase friction by making the surfaces of the object rough. We can also increase friction by pressing the two objects more strongly.
What two things affect the amount of friction between two objects?
The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface
What two things do you need to increase the kinetic energy of an object?
speed and potential energy
How do you find heat from friction?
When you rub two things together, the friction between the two things will produce heat.
What two factors determine the strength of friction between the two object?
The strength of the force of friction depends on two factors: the types of surfaces involved and how hard the surfaces push together.

Name two ways to increase friction?
Rougher surface and more weight to the object increases friction
What two things could you do to increase the momentum of the ball?
Reduce friction or increase slope.
When might you want to increase friction between two object?
Turning wheels against surfaces would require some amount of friction.
What two things affect the amount of friction between two objects?
The coefficiant of friction between the two surfaces and the normal reaction force of the object lying on the surface
What 2 things determine the friction between to objects?
Friction between two objects depends on the static coefficient of friction (if the object is currently not moving) and the normal force from the surface, acting in the direction opposite the direction of gravity.
Does friction cause more energy to be wasted if the object is heavier Why?
Friction between two objects = C X N. where C is the coeffiecient of friction for the objects in question, and N is the 'Normal' force. The normal force is the force equal and opposite to the object's weight. Therefore, if you increase the object's weight, the friction force increases, and the amount of energy wasted increases.
What two things do you need to increase the kinetic energy of an object?
speed and potential energy
What determines the force of friction between two objects?
Because Ffric = Normal force * coefficient of friction, and Fnormal = mass*9.81m/s^2, the coefficient of friction for those 2 objects, which represents the relationship between their touching surfaces, and the objects masses, are the two things that determine frictional force. As you probably can tell, the higher a coefficient of friction, the harder it is to move an object. Higher masses also increase the difficulty of moving an object because it results in a higher frictional force.

Describe two things you can do to increase the acceleration of an object?
Increase the force on the objectDecrease the resistance to motion (lubricate, remove resisting stuff like the air...)
