Force and Motion

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, either by starting to move, stopping, or changing direction.

Front

What is a balanced force?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

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 gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as speed = distance/time.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

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.
