mechanics

• Newton's third law of motion states that for every action, there is an equal and opposite reaction.
• Newton's second law states that the net force acting on an object equals the rate at which it changes momentum, or F = m * a
• The force on an object is the product of its mass and acceleration.
• Newton's first law of motion states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force.
• Normal force is the force exerted by a surface to support the weight of an object resting on it.
• The force exerted by the spring on the block is called elastic potential energy (Ep).
• The equation for acceleration (a) can be derived from Newton's second law by dividing both sides by mass (m)
• Acceleration is defined as the change in velocity over time, with units of meters per second squared (m/s^2).
• Velocity is defined as the speed of an object in a given direction, with units of meters per second (m/s).
• Mass is a measure of how much matter is present in an object, while weight is a measure of the gravitational pull on an object.
• Acceleration is the change in velocity over time.
• Velocity is the rate of change of displacement.
• Tension is the pulling force applied to an object when it is stretched or pulled.
• Weight is the gravitational pull on an object due to its mass.
• Elastic potential energy is stored when a spring stretches or compresses due to forces applied to it.
• Gravitational potential energy is the energy possessed by an object due to its position relative to another object with gravity.
• Kinetic energy is the energy possessed by an object due to its motion.
• Acceleration is defined as the change in velocity over time.
• Instantaneous velocity refers to the velocity of an object at a specific point in time.
• Average velocity is calculated by finding the total displacement divided by the number of intervals.
• Speed is defined as the magnitude or size of an object's velocity vector, without regard to its direction.
• Newton's first law states that if there are no forces acting on an object, it will continue moving at constant velocity.
• Motion can be described using graphs that show distance versus time, velocity versus time, acceleration versus time, and force versus time.
• Speed is the magnitude of velocity, measured in meters per second (m/s) or kilometers per hour (km/h), while velocity is a vector quantity that has both speed and direction.
• Newton's first law states that if no net force acts on an object, then the object will remain stationary or continue moving at constant velocity.
• The equation for acceleration (a) is a = delta v / delta t, where delta v represents the change in velocity and delta t represents the change in time.
• Displacement is the shortest distance between two points on a path, while distance traveled is the actual length of the path taken.
• The equation for average velocity is vavg = (Δx)/(t2 - t1).
• Newton's first law states that if there are no resultant forces acting on an object, then the object will remain at rest or continue moving at constant speed in a straight line.
• Average speed is calculated by dividing total distance traveled by elapsed time, while average velocity takes into account both displacement and direction changes.
• The unit of work done is joules (J).
• The equation for acceleration is a = vf - vi / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
• Work done is calculated using the equation W = Fd cosθ, where F is the force acting on the object, d is the distance moved, and θ is the angle between the direction of the force and the direction of movement.
• The acceleration of an object can be found using Newton's second law (F = ma), where F represents force, m represents mass, and a represents acceleration.
• The slope of a graph representing motion shows the average speed during that interval.
• Force is defined as any interaction between objects that causes them to exert a push or pull on one another.
• Force is defined as any interaction between objects that causes them to exert a push or pull on one another.
• Acceleration is the rate of change of velocity with respect to time, measured in meters per second squared (m/s^2).
• Distance-time graphs have units of meters per second (m/s) along the y-axis and seconds (s) along the x-axis.
• Acceleration is the rate of change of velocity with respect to time, measured in meters per second squared (m/s^2).
