Force and Motion

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting in the opposite direction to the movement.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It depends on the mass of the object.

Front

What is net force?

Back

Net force is the total force acting on an object, taking into account all the individual forces and their directions.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and there is no change in the motion of the object.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object, pulling it towards the center of the Earth.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented as p = mv.
