Motion

Front

What is the definition of force in physics?

Back

A force is a push or pull acting upon an object.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the motion of an object, causing it to slow down or stop.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the initial to the final position.

Front

How is speed defined in physics?

Back

Speed is the rate at which an object covers distance, calculated as distance divided by time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the relationship between mass and force according to Newton's second law?

Back

The force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the difference between average speed and instantaneous speed?

Back

Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the concept of inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the effect of gravity on motion?

Back

Gravity is a force that attracts objects toward each other, affecting their motion, especially in free fall.
