Front

What does it mean when an object is moving at a constant speed?

Back

An object is moving at a constant speed when it covers equal distances in equal intervals of time, without speeding up or slowing down.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in the motion of an object.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, representing the quantity of motion an object has.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the relationship between mass and velocity in momentum?

Back

Momentum depends on both mass and velocity; increasing either mass or velocity increases the momentum of an object.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).
