Speed is the distance traveled per unit of time, while velocity is a vector quantity that includes both speed and direction.
According to Newton's second law of motion, force is directly proportional to acceleration. This means that the greater the force applied to an object, the greater its acceleration will be.
Yes, an object can be in motion and still have a constant speed if it is moving in a straight line and its speed does not change.
Gravity is a force that attracts objects towards each other. It affects the motion of objects by causing them to accelerate towards the center of mass of the larger object.
Potential energy is the energy an object has due to its position or state, while kinetic energy is the energy an object has due to its motion. Both types of energy can be converted into one another, as stated by the law of conservation of energy.
