Physical Science Motion Test Review SY23-24

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

What happens to the weight of an object when it is on the moon compared to Earth?

Back

The weight of the object is less on the moon due to lower gravitational force.

Front

What is net force?

Back

Net force is the total force acting on an object when all the individual forces acting on it are combined.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, which is directly related to its mass.

Front

What is weight?

Back

Weight is the gravitational force acting on an object, calculated as mass × gravitational acceleration.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will resist changes in motion more.

Front

What is the relationship between speed, distance, and time?

Back

Speed is the rate at which distance is covered over time.

Front

What type of forces are required to change the motion of an object?

Back

Unbalanced forces are required to change the motion of an object.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, such as the Earth and an object.

Front

How do balanced forces affect an object's motion?

Back

Balanced forces do not change an object's motion; the object remains at rest or continues moving at a constant speed.
