What information do you need to find the motion of an object? Remember motion of an object also equals the speed of the object, so what two things do you need to know to find the speed of an object?

• The mass and length of the object.

• The distance an object moves and the time it takes to move that distance

• The direction of the object and the force of gravity acting on the object.

• The time the object moves and the mass of the object.
