physics

• The third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
• Acceleration is the rate of change of velocity.
• Newton's First Law of Motion states that objects at rest will remain at rest unless acted upon by an external unbalanced force, while objects in motion will continue moving with constant velocity (speed) unless acted upon by an external unbalanced force.
• Inertia is the tendency of an object to resist changes in its state of rest or uniform motion.
• Work done = force x distance moved in direction of force
• A force is a push or pull that causes an acceleration.
• Power (P) = energy transfer rate / time taken
• Weight is the gravitational pull acting on an object due to gravity.
• Kinetic energy is the energy possessed by an object due to its motion.
• The equation for work done is W = Fd cosθ where F is the magnitude of the force applied, d is the displacement of the point of application of the force, and θ is the angle between the line of action of the force and the displacement vector.
• The equation for kinetic energy is KE = 1/2 mv^2.
• The equation for work done is W = Fd cosθ, where F is the magnitude of the force applied, d is the displacement of the point of application of the force, and θ is the angle between the line of action of the force and the displacement vector.
• Energy can be transferred between different stores, but cannot be created or destroyed.
