Motion and Force

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in 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 the formula for calculating acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object in contact with a surface.

Front

What is gravitational force?

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.
