What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve changes in speed, direction, or both.

Front

What does it mean when a car has no acceleration?

Back

A car has no acceleration when it is moving at a constant speed in a straight line, such as when cruise control is set.

Front

What is friction?

Back

Friction is a force that opposes the sliding motion between two touching surfaces.

Front

What is net force?

Back

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

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a rock at the edge of a cliff.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and speed.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion and acceleration.

Front

What happens to the net force when two equal forces act in opposite directions?

Back

The net force is zero when two equal forces act in opposite directions.

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.
