Forces and motion

Front

What is a force?

Back

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

Front

What happens when the forces acting on an object are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the forces are combined.

Front

What is friction?

Back

Friction is the force that opposes motion between two surfaces that are in contact.

Front

What is motion?

Back

Motion is a change in an object's position over time.

Front

What is gravity?

Back

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

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity is speed in a given direction.

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

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

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).
