Front

What is frictional force?

Back

Frictional force is the resistance that one surface or object encounters when moving over another. It opposes the motion of the object.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be calculated as the change in velocity divided by the time taken.

Front

What happens to an object's motion if a net force acts in the direction of its movement?

Back

The object will speed up, not slow down.

Front

How do you calculate weight?

Back

Weight is calculated using the formula: Weight (N) = Mass (kg) × Gravitational acceleration (9.8 m/s²).

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which is dependent on its mass. Weight = Mass × Gravitational acceleration.

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
