Constant speed is

• Speed that does not vary and stays the same

• Speed at that exact moment

• Acceleration

What is the difference between speed and velocity

• speed is acceleration/ time and velocity is speed/time and direction

• velocity is distance/ time and speed is displacement/time and direction

• Speed is distance/ time and velocity is displacement/time and direction

net force

• Push or pull one exerts on another object

• The tendency of an object to resist a change in motion

• The sum of all forces acting on an object
