If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
The three types of acceleration in physical science are constant acceleration, variable acceleration, and instantaneous acceleration. Constant acceleration is when an object changes its velocity at a steady rate, variable acceleration is when an object changes its velocity at different rates, and instantaneous acceleration is the acceleration of an object at a specific moment in time.
1. You will have a uniform acceleration of about 9.8 meters/second2 when an object is in free fall near the Earth's surface - for example, when you drop an object, and air resistance can be ignored. 2. Any situation where the force is constant. 3. Uniform acceleration is often assumed for simplicity, for example, when accelerating a car.
When a body moves with uniform, its acceleration is is constant if v(m/s) t(s) a(m/s2) 4 1 0 8 2 4 12 3 4 16 4 4 (8-4/1)=4 12-8/1=4 hence acceleration is constant.
An object will remain at rest or in uniform motion unless acted on by an external force (law of inertia). The force acting on an object is equal to the mass of the object times its acceleration (F=ma). For every action, there is an equal and opposite reaction (law of action-reaction).

Velocity at time 0 sec = 0m per sec Velocity at time 3 sec = 45m per sec Acceleration is 45/3 = 15m per sec if the acceleration is uniform
He created 3 laws. The first one is force. The second about acceleration. The third about velocity.
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied. 2. The relationship between an object's mass (m), it's acceleration (a), and the applied force (F) is F=ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector. 3. For every action there is an equal and opposite reaction.

The three laws of motion are: First law (Law of Inertia): An object will remain at rest or in uniform motion unless acted upon by an external force. Second law (Law of Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Third law (Law of Action-Reaction): For every action, there is an equal and opposite reaction.
From a kinematic perspective, just observing the motion of an object, we can say that an object is experiencing uniform acceleration if the magnitude of the object's velocity changes at a constant rate but maintains the same direction. From a dynamic perspective, as a consequence of Newton's second law, we know that whenever the net force on an object is constant (in magnitude and direction) the object will undergo uniform acceleration.

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. III. For every action there is an equal and opposite reaction.
