What is displacement (d) in physics?

Displacement is the difference between the initial and final positions of an object.

How do you calculate velocity (v)?

Velocity is calculated using the formula v = Δd/Δt, where Δd is displacement and Δt is time.

What is the formula for acceleration (a)?

Acceleration is determined using the formula a = Δv/Δt, where Δv is the change in velocity and Δt is time.

How can you interpret distance-time graphs?

Distance-time graphs can be used to describe the motion of an object based on the slope of the graph.

How do you calculate speed from a distance-time graph?

Speed is calculated from the gradient (slope) of the distance-time graph.

What information do velocity-time graphs provide?

Velocity-time graphs can be interpreted to describe the motion of an object, including acceleration.

How do you calculate distance from a velocity-time graph?

Distance is calculated as the area under the velocity-time graph.

What is inertia?

Inertia is the property of an object that resists changes in its state of motion.

What is the relationship between force, mass, and acceleration?

The relationship is described by the formula a = f/m, where f is force and m is mass.

What are reaction forces?

Reaction forces are forces that occur in response to applied forces, such as support, reaction, or normal forces.

How do you calculate net forces from diagrams?

Net forces can be calculated by identifying and summing balanced and unbalanced forces in diagrams.

What are free body force diagrams?

Free body force diagrams illustrate all the forces acting on an object with proportional vector arrows.

What is tension in physics?

Tension is a reaction force that occurs in stretched or compressed objects.

What is the difference between static and dynamic friction?

Static friction prevents motion between stationary objects, while dynamic friction acts between moving objects.

What are non-contact forces?

Non-contact forces are forces that act at a distance, such as gravitational and magnetic forces.

How do you calculate gravitational force?

Gravitational force is calculated using the formula F = mg, where m is mass and g is the acceleration due to gravity.

What is the relationship between work, force, and distance?

Work is defined as the product of force (F) and distance (d) in the direction of the force.

How is work converted into energy?

Work can be converted into different forms of energy, such as kinetic or potential energy.

What is the principle of conservation of mechanical energy?

The principle states that the total mechanical energy in a closed system remains constant, barring non-conservative forces.

How do you calculate power (P)?

Power is calculated using the formula P = E/t, where E is energy and t is time.

How can power concepts be applied in real-life scenarios?

Power concepts can be applied to scenarios like lifting objects up ramps or vertically.
