Force and Motion

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction. Examples include friction, gravity, and applied force.

What does Newton's 3rd Law of Motion state?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. This means that forces always come in pairs.

Front

What are balanced forces?

Back

Balanced forces are equal forces acting in opposite directions on an object, resulting in no movement.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What is speed?

Back

Speed is the distance an object travels in a specific amount of time.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to move.

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 a force.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity. It is a measure of how difficult it is to stop a moving object.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the force that pulls us toward the Earth.

Front

What is a position-time graph?

Back

A position-time graph shows how the position of an object changes over time, helping to visualize its motion.
