Front

What is acceleration?

Back

Acceleration is the rate of change of velocity.

Front

What unit is used to measure force?

Back

Newton (N)

Front

What happens to a car's velocity when it experiences negative acceleration?

Back

The car's velocity decreases.

Front

How do you calculate net force?

Back

Net force is calculated using the formula: Net Force = mass × acceleration.

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the normal force?

Back

The normal force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = mass × gravitational acceleration.

Front

What does it mean for an object to have constant velocity?

Back

An object has constant velocity when it moves at a steady speed in a straight line without changing direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
